Dead End Clamps: Types

There are different clamps for holding wires on power lines. Each clamp has its own design. Some work better in certain places. Let’s learn about the main types and how they help keep power lines safe.

Compression Clamps

Compression clamps squeeze the wire tightly. You use special tools to close the clamp. This makes a strong grip that stays tight. These clamps are good for jobs that need strong, lasting support. You use them when you want the wire to stay in place for a long time.

Manufacturers say compression clamps are best for places needing a secure end. Hydraulic tools help you put these clamps on with the right force.

Wedge Clamps

Wedge clamps have a wedge part that pushes on the wire. When you pull the wire, the wedge gets tighter. This holds the wire in place. Wedge clamps are easy and quick to install. They work well where wires need to be held tightly.

You use wedge clamps for overhead lines that need strong ends. These clamps stop wires from slipping and keep them straight.

Bolted Clamps

Bolted clamps use bolts and nuts to lock the wire. You tighten the bolts so the wire does not move. Bolted clamps are simple to put on and adjust. You can use them for wires above ground or underground.

Bolted clamps follow rules like IEEE C135.64-2012 and IEEE C135.100-2024. These rules help you test and pick the right clamp for your job.

Application Differences

You need to choose the right clamp for each job. Here is a table to show where each type works best:

Tip: New clamps use strong aluminum and materials that do not rust. These features make clamps easier to install and help them last longer.

You can pick the best clamp by thinking about your needs and the weather. Dead End Clamps help keep power lines safe and working well.

Dead End Clamps: Installation

Installation Steps

You must follow the right steps to install Dead End Clamps. Here is an easy guide to help you:

1. Get your ratchet lever hoist and wire grip ready. Use shackles if you need them.
2. Pull the strap hoist until the cable matches the end spot.
3. Tighten the strap a little more. This keeps tension after you take off the hoist. Do not go past the tension limit from the maker.
4. Take the mooring hook off the clamp. Put the hook at the support spot and fix it inside the clamp body.
5. Take out the wedge from the clamp. Put the cable inside the clamp, then put the wedge back in.
6. Use the lever hoist handle or drum knob to let the tension out slowly.
7. Make sure the cable is tight and does not move.
