Product Description
For more information, please visit pg clamp is used for.
PG clamp is known for parallel groove clamp, especially used in transmission line to hold transmission conductors in parallel.
PG Clamp solutions offered provides for secure holding support of transmission conductors. These parallel groove clamps come with features like high corrosion-resistance, aluminum alloy construction in hot forged finish, stainless steel based bolts & nuts in hot-dip galvanized finish, corrosion protected washer support, precision developed pressure pads with spring washers in hot-dip galvanized finish, copper based conductors and others. We can also custom design and develop these clamps as per the specific requirements of the customers.
1. What is a parallel groove clamp (PG clamp)?
A PG clamp is an electrical accessory used to connect and secure overhead power lines, conductors, or cables to various types of support structures, like poles or towers.
2. How do PG clamps work?
The parallel groove clamp is used to connect ACSR and aluminium conductors with high strength aluminium alloy.
3. How are PG clamps installed?
PG clamps are typically installed by trained technicians.
Do not cut the strands from the conductor or double over strands of the conductor to make it fit until you get the correct size of the clamp.
Make the PG clamp and conductor ready by brushing the contact surfaces to remove the oxide.
Lavishly apply grease over the brushed area of the conductor only to ensure that the entire area is being covered properly.
4. Are PG clamps suitable for both low and high-voltage applications?
Yes, PG clamps are versatile and can be used in both low and high-voltage applications, making them suitable for various electrical systems.
The aluminum PG clamp / parallel groove clamp is used for the connection of small and medium cross-section aluminum stranded wire that does not bear tension. It is also used for the jumper connection of non-linear poles. Power engineering materials (fittings) are used for interconnection of connecting wires, which are mainly used in power line engineering.
The aluminum PG clamp PG 660 series is our hot sale product selling wordwide.The main cable range and service cable range from 16 to 300 sqmm.It is used to connection AL -AL conductor.If the cable contains an insulating sheath, the insulating sheath must be stripped before using the parallel groove clamp for paralleling. It is not like a piercing clamp that can be pierced into the insulating sheath.

The parallel groove clamp is made of plate-plate structure and aluminum alloy material.
Relying on the tightening pressure of bolts, the connected wires are fixed in the upper and lower grooved splints to complete the connection, and then transmitted through flat washers and spring washers. Provides a relatively uniform and constant pressure effect on the connecting wires. It can be disassembled after installation. It is often used at the jumper or ground wire lap joints at the strain end of the line. In order to ensure that the clamp has sufficient and even pressure on the wire, it is grooved. The parallel groove clamp generally adopts a two-bolt or three-bolt structure, and the installation requires uniform force when tightening the bolts. Sometimes in order to ensure the reliability of operation, two or three clamps are connected in parallel at equal intervals during line construction. The holding force of the bolt-type parallel groove clamp to the wire is about 10%-20% of the calculated breaking force of the wire.
