How to Install 252LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of 252LR Deadbreak Elbow Connectors, designed to terminate UD jacketed and non-jacketed cables and connect to 12/20 (24)kV 250 ampere deadbreak bushings or accessory devices. All apparatus must be de-energized during installation.
Estimated time: 1h 30m
Tools needed:
Wrench, Hotstick (fully insulated), Wire brush, Crimp tool (refer to lug chart), Wire strippers, Suitable sensing device (for capacitive test points)
Supplies needed:
Elbow Connector Housing, Compression Lug, Probe, Probe Contact, Lubricant (supplied), Hold-down Bail, No. 14 AWG / 2.5mm copper wire, Appropriate connector (for neutral to ground), Cold shrink tube (optional, for sealing kits), Conductive copper tape (optional, for copper tape shield cable), HV insulated cap(s) or connector(s) (if replacing shipping covers)
- Perform Initial Safety Checks and Cable Training
DANGER: Ensure all apparatus is de-energized before beginning installation. Inspect all parts for damage, correct rating, and compatibility with mating parts. Read the entire installation instruction, check package contents, and verify the elbow housing cable entrance size and compression lug size for proper fit. Train the cable to ensure sufficient slack for ease of operation. Based on your cable type (non-jacketed concentric neutral, jacketed concentric neutral, jacketed with drain wires, or jacketed copper tape shield), follow the specific instructions in the product documentation for initial jacket removal, unwrapping/binding neutral or drain wires, and cutting the cable squarely at the bushing centerline. If using a sealing kit, slide the cold shrink tube onto the cable at this stage.
- Prepare Conductor and Insulation
Remove 2-1/8” (55mm) of the shield and insulation from the cable end, cutting squarely and taking care not to nick the conductor. Wire brush bare aluminum conductors thoroughly and immediately place the compression lug over the conductor, rotating to spread the inhibitor. Position the compression lug so its threaded hole aligns with the bushing bore. Crimp the lug according to the crimp chart, starting at the crimp line mark and rotating 180 degrees for each successive crimp. Carefully wipe any excess inhibitor from the outside of the lug and cable. Remove the insulation shield as shown in the product documentation (typically 6-7/8” (175mm) from the cable end) and bevel the insulation end 1/8” (5mm) maximum. Thoroughly clean the insulation to remove all traces of dirt or excess inhibitor.
- Assemble Elbow Connector
Clean the cable insulation and the inside of the elbow housing, then lubricate with the supplied lubricant. DO NOT SUBSTITUTE other lubricants as they may be harmful. Slide the elbow connector onto the cable using a back-and-forth twisting motion. Wipe off all excess lubricant. Align the elbow with the compression lug’s threaded hole. Thread the probe into the lug by hand, taking care not to cross-thread, then tighten with the supplied wrench until the wrench bends.
- Assemble Hold-down Bail
Place the hold-down bail into the hold-down bracket, ensuring it is properly seated and ready for securing the elbow.
- Connect Concentric Neutral
Using a separate No. 14 AWG / 2.5mm copper wire or equivalent, insert one end through the grounding eye on the elbow and twist tightly, taking care not to damage the eye. Twist all neutral wires together and connect them to ground using an appropriate connector, providing adequate slack in the wires for elbow operation.
- Connect Elbow to Bushing Plug
Clean the receptacle portion of the elbow connector and the mating bushing. Lubricate these surfaces ONLY IF the transformer and elbow are known to be de-energized. Use a fully insulated hot stick to place the elbow onto the bushing. DO NOT OPERATE BY HAND. DO NOT SEPARATE IF ENERGIZED.
- Secure Elbow with Bail
Pull the hold-down bail up over the crown or top of the elbow so that the eyebolt on the bail is directly over the operating eye. Tighten down on the elbow locator by turning the eyebolt in a clockwise direction. Adjust the nut on the eyebolt until it allows the eyebolt to seat securely in the locator. The nut should act as a stop to prevent the eyebolt from applying excessive force on the elbow. Once the nut is in its final position, it will not need to be readjusted when removing and replacing the elbow.
- Perform Voltage Test (Optional but Recommended)
If performing a voltage test, remove the test point cap with a hotstick, peeling it off at an angle rather than pulling directly. WARNING: The voltage test point is a capacitance device and is not directly connected to the conductor. Do not use conventional voltage measuring equipment. Follow the manufacturer’s directions for the suitable sensing device used with capacitive test points to determine if the cable is energized. Contamination or incorrect equipment can provide a false “no voltage” indication; treat the elbow as energized until confirmed by other means. After testing, clean the inside surface of the cap, lubricate with silicone lubricant, and replace it on the test point.
