What Are the Equivalents of Medium Voltage PG Clamp SL4.25, SL37.1, SL37.2 Made in China?

A PG clamp is a type of electrical connector commonly used in medium-voltage (MV), high-tension (HT line) power systems. Its primary function is to securely connect, terminate, or branch electrical conductors while ensuring electrical continuity and mechanical stability.

Jera Line has been a leading manufacturer specializing in low-voltage and medium-voltage cable accessories for over ten years. As well as parallel groove clamps that also produced by Jera Line, which are the equivalents of SL4.25, SL37.1, SL37.2 PG clamps, and the specifications are as below:

• Comparison Chart

• Key Features

1. High mechanical strength for long term application
2. For medium voltage ht line (above 10kV) usage
3. Jera Line’s pg clamps are suitable for a wide cable size range
4. Compact size with light weight, offering reduced load on the transmission line
5. Excellent environmental stability and corrosion resistance
6. Competitive prices benefit from the location in China

• Application

1. Medium-Voltage Cable Routing and Fixation
2. Vibration Dampening and Stress Relief
3. Bypass or temporary connections during maintenance work
4. T-branch connections for extending or branching a circuit

• Installation Steps

1. Preparation and Inspection: ensure all tools, materials, and safety measures are in place
2. Clean the Conductors and Clamp: ensure the conductor without oxidation, rust, or dirt.
3. Position the Conductors: Place the two parallel conductors side by side, aligning with the groove.
4. Tighten the Clamp Bolts: Use a torque wrench to tighten the bolts gradually and evenly, and avoid over-tightening.
5. Final Inspection: Ensure the clamp holds the conductors firmly and check for low resistance across the connection (high resistance indicates poor contact).

It is easy to install, and only needs one skilled worker to conduct it.
