About this product

Product information from the supplier.

The Parallel Groove Clamp is a high-performance electrical connector engineered for the precise splicing of aluminum stranded wires and steel core aluminum stranded wires. Designed specifically for power and communication lines, this versatile fitting ensures a stable, low-resistance electrical connection in positions that do not bear tension, such as overhead lightning protection lines and route connections for non-linear towers.

By leveraging advanced bolt-pressure technology, our parallel groove clamps provide a secure mechanical grip that eliminates potential contact failure caused by vibration or environmental stress. Whether you are managing small or medium cross-section wires, these clamps deliver the durability and conductivity essential for maintaining the integrity of modern electrical infrastructure.

Frequently Asked Questions

Q: What is the primary use of a Parallel Groove Clamp?

It is primarily used for splicing aluminum or steel core aluminum stranded wires in power and communication lines, specifically in non-tension positions and jumper connections.

Q: Can these clamps be used for copper wires?

Yes, parallel groove clamps are designed to be compatible with various wire types, including bare aluminum, aluminum alloy, and copper wires.

Q: How does bolt pressure affect the electrical performance?

Bolt pressure creates the necessary mechanical force to ensure a tight contact between the wire and the clamp, which minimizes resistance and ensures stable current flow.

Q: What materials are used to prevent corrosion in outdoor settings?

We utilize high-grade aluminum alloys, galvanized steel, or stainless steel, often enhanced with specialized anti-corrosion coatings for maximum durability.

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

The JB type aluminum parallel groove wire clamp is specifically suitable for splicing aluminum and steel core aluminum stranded wires with cross-sections from 16mm² to 240mm².

Q: Do I need special tools for installation?

No, the design allows for fast installation. Simply place the wire into the groove and tighten the bolt using standard wrenches, which significantly improves work efficiency.
