Frequently Asked Questions

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

It is used to connect two or more parallel power wires, specifically aluminum stranded or steel core aluminum wires, ensuring a stable electrical connection in non-tension positions.

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

No, parallel groove clamps are specifically designed for positions that do not bear tension, such as jumper connections or lightning protection lines.

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

Our clamps are typically made from aluminum alloy, galvanized steel, or stainless steel, often featuring specialized corrosion-resistant coatings for longevity.

Q: What wire sizes are compatible with the JB type clamp?

The JB type aluminum parallel groove clamp is designed to accommodate aluminum stranded and steel core aluminum stranded wires ranging from 16-240mm².

Q: How is the electrical performance of the clamp maintained?

The electrical performance relies on the bolt pressure to create a tight mechanical bond, which reduces resistance and ensures efficient current flow.

Q: Are special tools required for the installation of these clamps?

No special tools are required; the installation process involves placing the wire into the clip slot and tightening the bolt, significantly improving work efficiency.
