Parallel Groove Clamp

Parallel groove clamps are used to connect small and medium-sized aluminum stranded wires or steel-core aluminum stranded wires and steel stranded wires of overhead lightning protection wires in positions that do not bear tension. They are also used for jumper connections on non-linear poles and towers. Electric power engineering materials (fittings) are mainly used for connecting wires to each other in power line engineering.

Specification Introduction

Product Feature

  1. Use high-strength, corrosion-resistant aluminum alloy and hot-forged bimetallic sheets
  2. Tooth-shaped structure, low contact resistance, reliable connection
  3. The components are integrated and will not fall out during installation.
  4. The arc hugs a large area and the contact surface is closer. Improve the clamp’s grip on the conductor

 

Insulation Cover Performance Feature

  1. Power frequency withstand voltage: ≥ 18kV, no breakdown after maintaining voltage for 1 minute
  2. Insulation resistance: >1.0×102 Ω
  3. Ambient temperature: -30℃~90℃
  4. Weather resistance: good performance after artificial climate aging test.

 

Application

In the power industry, parallel groove clamps are widely used for connecting and fixing cables. In power transmission lines, in order to ensure continuous transmission of power, different sections of cables need to be connected. In this case, parallel trench clamps are needed. The parallel groove clamp has good electrical conductivity and mechanical strength, which can ensure the stability and safety of power transmission.

 

In the construction industry, the installation and maintenance of electrical equipment is critical. Parallel trench clamps can be used to connect and fix cables to ensure the power supply inside the building. In construction sites, in order to facilitate the operation and maintenance of construction workers, parallel trench clamps are usually used to fix cables on the wall or the ground to prevent the cables from loosening or being damaged.
