Insulated By-Pass Jumpers
Insulated By-Pass Jumpers
  • Rated for 15 kV phase-to-phase systems

Center support for easy applications
Available in four jumper-cable sizes, this by-pass jumper design features mid-span an orange 8-foot-Iong epoxy-resin, fiberglass-reinforced-plastic (FRP) tube. The rigid 1/2-inch­ O.D. tube serves as a support for easy handling of the jumper set by rubber gloves or hot-line tools. This makes the unit especially handy when jumpering switchgear, reclosers or cutting in double deadends.

Completely pre-assembled
Two non-metallic hangers - one at each end of the FRP support tube - provide for parking the by-pass clamps while moving the jumper set into or out of the work area. Since the 16-foot-long jumper cable (with EPR jacket) is secured where it exits the FRP tube, 4 feet of cable extend from both ends of the rigid support.

Threaded compression assemblies - each comprising a connector, nut and lockwasher, all of copper - are applied at the cable ends. Two clamps (each a Chance C6001743) also come installed with cable strain-relief clamps to complete the by-pass jumper set.

Ordering Information for Insulated Jumper Sets:
Each: 16-ft. overall length (includes 8-ft. tube) with two C6001743 clamps applied on cable by copper connector assemblies

Load Pickup Tool
Load Pickup Tool
  • Rated for loads as high as 250 amperes
  • For 15kV systems
  • Fits #6 Copper through 795 kcmil ACSR

This tool can be used to pickup loads and carry 250 Amps at 15kV. Rubber gloves should be worn while installing. The head has a floating washer to minimize conductor damage as the jaws are installed. The contacts are spring loaded and can be closed by pulling an insulated lanyard, putting the operator away from the tool during pickup operations. The contacts cannot be teased closed.
The tool cannot be used as a load-break tool as the operator cannot open the contacts while the tool is on the conductor. A fiberglass rod, attached to the end of the lanyard, is used to recock the contacts, but because it must be inserted through the head of the tool, the lineman must remove the tool from the conduc­tor before recocking.
An orange-tinted clear Lexan® housing permits easy visual inspection. A nylon handguard is used to keep the lineman's hand away from the energized area. By simply removing two screws in the handguard, the tool can be disassembled for inspection and maintenance.
All current carrying parts are copper or copper alloy and contacts are silver plated.
The recommended 15kV jumper cables for this tool are #2 and 1/0.
It is recommended that the Load-Pickup Tool be inspected and cleaned after 25 operations or after 90 days. Clean all plastic parts with a soft cloth, damp with ethyl alcohol only.

The contacts are opened by passing the recocking rod through the head on the tool and pushing the plunger to its fully opened position. This operation cannot be done when the tool is connected to the conductor.

Electrical Ratings: Nominal 15kV 3-phase or 8.3kV single phase circuits; 250 amps continuous current.
Main Line Range: #6 Copper (0.162") minimum through 795 kcmil ACSR (1.108") maximum.

Temporary Load Disconnect Tools
Temporary Load Disconnect Tools

8.3/15kV & 15/27kV applications*
Superior design
Available in two sizes, this tool provides a temporary means of connecting and disconnecting equipment or circuits under load conditions. This tool design does not have a fuse and does not provide protection for fault or overcurrent conditions. Insulated bushing and hot parts are from Chance Type C-Polymer cutouts, including the tubular-copper disconnect blade.
An arc-chute-type interrupter gives the tool its excellent loadbreak capability. To interrupt load currents, the device makes use of a stainless-steel auxiliary blade within a Delrin® arc chute.
The tool simply clamps onto primary conductor with a Grip­All clampstick. Bronze stud at lower end accepts clamp on temporary tap jumper.
Easy operation
This self-contained loadbreak device operates by a simple disconnect stick. No special or portable tools are required to operate the unit.
To break the current, just insert a disconnect stick into the operating ring and rapidly open the device. In the process of opening, the spring-loaded auxiliary blade snaps out through the arc chute to elongate, cool and extinguish the confined arc. This loadbreaking operation is independent of the dis­connect stick speed.
To provide a clearly visible break, the disconnect blade hangs in approximately a vertical position.
Unfused or unswitched loads can be disconnected by first installing this tool and a temporary bypass jumper in parallel with the permanent tap connection. After closing the blade of the tool, the permanent tap can be disconnected. The load can then be dropped or reconnected by operating the blade of the tool. It should never be closed into a fault or opened during a fault.
Simple installation and removal
To install the tool, first remove its main blade. Then secure both clamps of a suitable temporary jumper onto the tap stud of the tool's lower hinge.
Use a Grip-All clampstick to install the tool onto the main line conductor. Use the clampstick to secure one of the jumper clamps onto the line with the load to be picked up.
Use a disconnect stick to place the blade in the lower hinge of the tool. Use the disconnect stick in the operating ring to close the blade according to safe work procedures. Take care when removing the disconnect stick to avoid opening the blade.
The equipment or circuit is now energized through the tool. Before removing the tool, first make up a permanent connec­tion so there are two energizing paths.
Use a disconnect stick in the operating ring to open the blade according to safe work procedures and to remove the blade from the lower hinge of the tool. Use a clampstick to take the jumper clamp from the conductor and secure it on the tool stud. Then use the clampstick to remove the tool from the main line conductor.

Tension Puller Switching Tool
Tension Puller Switching Tool

Tension Puller Switching Tool

  • For line tension up to 4,000 lb. with manual hookstick switch
  • Maximum ratings: 35 kV 0-0, 600 amps continuous, 150 kV BIL
  • U.S. Patent 4,661,662 and subject to patents in certain other countries

Applications and design
This tool permits a live overhead distribution line to be cut. By bearing the mechanical load, it helps create a parallel circuit. This averts service interruption while the cutting and related work are performed. It may be applied wherever a disconnect switch is desired for temporary sectionalizing and the tool is properly rated concerning line tension, continuous current, BIL and system voltage.
Applications that require cutting a conductor include:

  • Deadend-structure construction
  • Overhead switch installation on a structure
  • In-line switch installation.

The Tension Puller Switching Tool basically combines two Chance products: Epoxiglas® insulated tension puller and LTD® line-tension disconnect switch.
For this special tool, weathershed skirts of a tough, light­weight polymeric have been bonded to the tension puller's 1-1/2"-diameter Epoxiglas pole. At both ends of the skirts, a locating pin aligns a compression clamp to secure the switch hot parts to the pole.
A bypass stud (1/2”-dia.) added at each end of the switch accepts clamps up to 3" wide. The rigid, H-frame copper switch blade opens to a standard 90°, or to 180° with a stop pin re­moved. Contact areas are silver-plated for high conductivity. Galvanized-steel hooks are provided for use with a portable loadbreak device. For easy opening and ice-breaking, the pull ring (1-1/4"-dia. eye) activates latch as a pry-lever.
Hooks on ends are fixed so as not to swivel. Safety latch on hooks has a spring-loaded gate able to rotate 135 de­grees left or right from the closed position.
Selector lever on ratchet wrench is extra large for easier operation by hot line tools.
Installation and operation
Equipped with rings, this tool may be handled and operated by either hot-line tools or rubber-glove live-line techniques. Illustrated instructions included with each unit give applica­tion considerations and procedures for installation, operation and maintenance.
Suspended from hot-line wire grips with the disconnect switch closed, the tension puller works like a jack. Operating the ratchet wrench brings the tool's two ends closer. This reduces tension on the conductor between the tool's hooks.
Hot line jumpers sized to the application are installed on the conductor and the tool's bypass studs to create a parallel circuit. Before cutting the conductor, it is securely restrained. Once cut, its long tail is clamped back onto itself.
A properly rated portable loadbreak device may now be hung on the tool's disconnect hooks and used to open the switch.
For additional recommendations, refer to ANSI C37.35 IEEE Guide for the Application, Installation, Operation and Maintenance of High Voltage Air Disconnecting and Load Interrupter Switches.
