About this product

Product information from the supplier.

The Parallel Groove Clamp is a high-precision electrical connector engineered for the seamless splicing of aluminum stranded wires and steel-core aluminum stranded wires. Specifically designed for small and medium cross-sections, this essential fitting is optimized for overhead lightning protection lines and non-linear tower route connections where tension is not the primary load, ensuring a stable and low-resistance electrical path.

By leveraging superior bolt-pressure technology, the Parallel Groove Clamp achieves a robust mechanical grip and exceptional conductivity. Whether used in power distribution or communication networks, its versatile design accommodates a wide range of conductor types, providing a reliable interconnection solution that withstands environmental stress and ensures the continuous stability of power transmission.

Frequently Asked Questions

Q: What materials are primarily used in Parallel Groove Clamps for durability?

They are typically manufactured from high-conductivity aluminum alloys or galvanized steel and stainless steel to ensure maximum resistance to atmospheric corrosion in outdoor power environments.

Q: Can these clamps be used for high-tension power lines?

Parallel Groove Clamps are specifically designed for positions that do not bear tension, such as jumper connections or lightning protection lines, rather than main tension-bearing spans.

Q: What is the applicable wire range for the JB type clamp?

The JB type aluminum parallel groove wire clamp is designed to support aluminum and steel-core aluminum stranded wires with cross-sections ranging from 16mm² to 240mm².

Q: How does the Parallel Groove Clamp ensure a stable electrical connection?

It relies on precisely engineered bolt pressure to clamp the wires firmly into the groove, minimizing contact resistance and preventing disconnection caused by vibration.

Q: Are these fittings suitable for copper conductors?

Yes, the design is versatile and suitable for connecting various wire types including bare aluminum, aluminum alloys, and copper wires.

Q: What are the main applications of electrical fittings in power line engineering?

Electrical fittings are used for interconnecting wires, securing conductors to towers, providing lightning protection, and managing route connections in both power and communication grids.
