Coverup Equipment
Cutout Covers

Cover-up equipment is finding increasing usage on all types of high-voltage line maintenance. Most of the individual pieces can be installed with rubber gloves, or else they are equipped with hot stick application eyes. Common sense rules must always be followed when using cover-up equipment. These rules include:

  1. Cover-up equipment (such as line covers, insulator covers, cutout covers, and deadend covers) is intended to prevent personnel from making accidental brush contact with energized parts or equipment. Under no conditions should personnel purposely contact the covers, except with adequate rubber gloves, and personnel must always be aware of their position in order to avoid accidental contact with the cover.
  2. Cover-up equipment (such as pole covers, crossarm guards, crossarm end covers, and pole top covers) is intended to help prevent accidental contact of energized tie wires or conductors with the grounded surface of the pole or crossarm.
  3. Cover-up equipment must be handled with care to minimize breakage and scratching, and it must be kept clean. Maintenance is as important with cover-up equipment as with hot line tools. Each cover must be thoroughly inspected before each use to ensure that it has no cracks, deep scratches, or gouges and to ensure that it is clean. Cleaning should be done with a wiping cloth, and if that does not remove all dirt, mild soap and water should be used. Polyethylene covers can be cleaned with Chance Moisture-Eater II (U.S. Patent 5,405,547) solvent-cleaner. Caution: Solvents must be avoided unless the user can determine that the material in the particular cover is polyethylene.
  4. For Temporary Use — Cover-up equipment is designed to be as light and easy to use as possible, hence it is not made from materials that can withstand extended periods of electrical stress. Therefore, Chance cover-up equipment must not be left installed for extended periods, especially if allowed to touch both an energized surface and a possibly grounded surface. The situation would be highly aggravated in rainy or humid weather, when the surfaces of the covers become dirty, etc. Therefore, the covers should be removed at the end of the workday, if at all possible.
    • Tested to ASTM F712.
    • Manufactured to ASTM F968 specifications.
    This cover aids in the protection of linemen working near most open-type cutouts rated at 25kV or under, but it will not fit over cutouts with linkbreak levers or similar devices. It can be placed over the cutout, and then a locking pin slips behind the cutout insulator over the hanger bracket and into a hole on the opposite side of the cover.
    Eyes on both the cover and locking pin allow installation with a Grip-All clampstick.
    This cover is made of orange high-impact ABS plastic. Several units can be nested together for convenience and space saving on the truck.

Pole Covers 36.6 kV Phase-to-Phase

  • Tested to ASTM F712
  • Manufactured to ASTM F968 specifications
  • Meet Class 4 requirements

These pole covers are used to help protect personnel when raising or lowering a pole between energized lines or to cover poles when rubber glove maintenance is performed in rela­tively confined areas. The covers are made of high-dielectric linear polyethylene material that will not flash flame. This material will have some softening without deformation at approximately 170°F, and it will resist brittleness at temperatures to -50°F. All Chance pole covers are ribbed to reduce cover contact with the pole, thus minimizing creosote contamination.
Anylon button on 4- and 6-foot lengths allows the pole covers to be joined together in tandem, where longer lengths require covering. The rope handles permit personnel to easily spread the covers and snap them around the pole; rubber gloves must be worn during this procedure. Prolonged contact with an energized conductor must not be allowed.

Covers for Conductors, Insulators & Deadends
Conductor Covers   Cover Types

Covers for Conductor, Insulators and Deadends
• 36.6 kV Phase-to-Phase
• ASTM Class 4
• Tested to ASTM F712
• Manufactured to ASTM F968 specifications
These covers provide a highly versatile system of covering up a wide variety of configurations on distribution systems. The conductor covers couple with the insulator units and deadend units to cover pin-type or post-type insulator construction. Together, they virtually surround the hot parts and hardware to give lineworkers extra protection when rubber gloving or using hot sticks. Each item is fitted with an adapter for multi-position handling by Grip-All clampsticks.
These covers also couple with Chance 25 kV covers, Classes 2, 3 and 4 of rubber line hose and major brands of rubber insulator hoods.
All covers are bright orange in color. All are made of of high­density polyethylene in a uniform wall thickness for excellent dielectric/puncture strength and perform well from -50° to 170°F. Ultra-violet stabilizers in the material help inhibit degradation as a result of atmospheric exposure.
Conductor cover is 5 feet long. The cover's V-shaped bottom edge makes it easy to install. Four indented ribs along the cover's top edge provide an air gap between the conductor and the cover. Maximum conductor size is 666 kcmil ACSR.
Insulator covers come in two heights. Either 12" or 16-1/2" tall cover fits 6-1/2" to 9"-diameter pin or post insulators. Special slits in the insulator covers help locate the conductor and hardware when installing the covers.
Deadend cover fits three 10"-diameter porcelain bells or polymer deadend insulators and couples with the line cover. To meet the Class 4 rating, the deadend cover must be used in conjunction with a rubber insulating blanket covering the coupler to the line cover. Failure to use a blanket to cover the coupler may result in electrical shock, severe injury or death by electrocution.

Conductor & Insulator Covers

These covers are made of high-dielectric polyethylene. The wax-like surface provides a natural self-cleaning action and resists the effects of greases and other contaminants. The bright-orange color gives a visible warning to those who are working close to the equipment.
Chance conductor and insulator covers are designed to help protect the lineman while working close to energized conduc­tors . They are rated phase-to-phase for voltages through 46kV and can be easily installed with a Grip-All clampstick.
The conductor cover clips on and covers conductors up to 2 inches in diameter. A positive air gap is maintained by a special hanger system inside the cover. The conductor is locked in the hanger by a swinging latch that can be opened and closed with a hot stick.
The insulator cover is designed to be used in conjunction with two conductor covers on insulators above 13kV. It fits over the insulator and locks with a conductor cover on each end. A polypropylene rope swings under the crossarm and hooks with a clampstick, thus helping to prevent the insulator cover from dislodging due to bumping or wind gusts.

Low weight, high performance
Much lighter in weight than other flexible dielectric cover­up, Chance Line Hose helps protect workers from accidental contact with conductors.
In accordance with ASTM D 1050-90, Chance ozone/corona­resistant thermoplastic elastomer offers excellent perfor­mance properties. It does not absorb water.
Easy to handle and place: The outer lip peels back with ease to open and start onto a conductor from either end. With a push at the other end, the full length slides on as the lips zip closed around the conductor. To remove each piece, open one end and strip the remainder off the conductor.
Excellent color retention: To retain its original color, Chance hose has superior resistance to long-term ageing/checking.
Serrated external ribs permit coupler to engage grooves inside long arm on flexible hoods made by others. Resilient lips overlap to sur­round conductor.
Parallel grooves inside coupler match and grip the 20 serrations (1/4" each) in outside ribs. All serrated sections measure 5" long. Coupler overlaps 6" onto plain end.
Interchangeable with other flexible cover-up brands, Chance Line Hose also engages Chance rigid-type insulator hoods, deadend covers and lineguards (rated for 25kV phase-to-phase).

Extended Lip Flexible Line Hose
Extended Lip LIne Hose

Low weight, high performance
As much as 25 percent lighter in weight than other Class 4 flexible cover-up, Chance Line Hose helps protect workers from accidental contact with conductors.
In accordance with ASTM D 1050-90, Chance ozone/corona-resistant thermoplastic elastomer offers excellent perfor­mance properties. To retain high-visibility orange color, the special formulation exhibits superior resistance to long-term aging/checking. It does not absorb water.
The dielectric cover-up system consists of a separate coupler and three popular hose lengths. This permits hoses to join to cover straight runs or to flex to fit contours at bends and angles. Shorter sections may be cut on site from standard lengths to custom-fit taps, jumpers and like wires.
Easy to handle and place
Rubber gloves or hot-line tools may be used to apply Chance Class 4 Line Hose.
In addition to lightweight, the balanced material composition in Chance line hose also gives it pliability. This makes it easy to put on, couple, relocate and remove, unencumbered even when wearing leather protectors over rubber gloves.
The outer lip peels back with ease to open and start onto a conductor from either end. With a push at the other end, the full length slides on as the lips zip closed around the conductor.
So the hose can readily insert into the coupler, Chance bevel-cuts the serrations on the side ribs. The vertical serrations resist withdrawal from the coupler. Coupler also can join sections Chance 1-1/2"-diameter short-lip Class 3 hose for 26.5 kV phase-to-phase maximum use.
Two or more coupled sections stay joined when drawn along on the conductor and positioned as a unit. The rubber-like material slides readily by hand yet resists creep or slippage when placed. To remove each piece, open one end and strip the remainder off the conductor.
Parallel grooves inside the coupler match and grip the 28 serrations (1/4" each) in Class 4 hose ribs. All serrated sections on Class 4 hose measure 7 inches long. Coupler overlaps 5-1/4” inches onto hose when engaged.

Arc-Supression Blankets
Arc Suppression Blankets

Arc-Suppression Blankets (Not Electrically Insulated)
• For shields against electrical fault blasts
Heavy-duty protection in lightweight package
Two synthetic fabrics are combined in the ArcSafe™ Suppression Blanket from Workrite (Your Uniform for Life Company). Both space-age fabrics are aramid-fiber types. The inner layer is Kevlar® and the outer is NOMEX ®III.
Kevlar is the same aramid fiber used in combat helmets and body armor. Flame-resistant NOMEX III is used as the cover to protect the Kevlar core from ultraviolet degradation.
Because the blankets consist of thin layers, ArcSafe blankets offer unrivaled portability and are extremely easy to maneuver in confined spaces. They weigh only 1/5 pound per square foot (5/8 kg. per m2).

Applications and conforming to OSHA law
When draped or loosely wrapped over a defective cable or splice, ArcSafe provides a protective shield for exposed workers. Velcro® straps sewn on the back help keep ArcSafe where positioned. ArcSafe blankets meet or exceed OSHA requirements for manhole protection.
Beginning in 1991, OSHA mandates that if cables in manholes appear defective ... " ... and cannot be de-energized due to service load conditions, employees may enter the manhole provided they are protected from the possible effects of a failure by shields or other devices that are capable of containing the adverse effects of a fault in the joint." [29 CFR Part 1910.269(t)(7)]

Tested successfully at 42,000 amps fault current. ArcSafe was subjected to fault-current testing at Chance laboratories. ArcSafe was placed over a small section of 2/0
copper cable that was faulted to ground, simulating a cable or splice failure. The maximum fault current generated was 42,432 amps for a duration of 13 cycles.
Other than black deposits, ArcSafe experienced no damage and provided total fault-blast containment.
