Table of Contents

Commonly used busbar materials include copper, aluminum, and steel. Commonly used busbar types include stranded steel core aluminum stranded wires (overhead wires), aluminum busbars and copper busbars, and tubular busbars.

aluminum tubular busbar

In the power system, the busbar connects various current-carrying branch circuits in the power distribution device and plays the role of collecting, distributing and transmitting electrical energy. Xienuo can produce busbar such as aluminum busbar, tubular aluminum busbar and composite shielded insulated aluminum tubular busbar.

What is tubular aluminum busbar

Aluminum alloy tubular busbar also know as aluminum bus pipe tube, it is one of the main products of busbar and one of the key equipment in power transmission and transformation system. It plays a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment.

Tubular aluminum busbar is a new conductor that replaces the traditional flat busbar, rod-shaped busbar and multi-strand steel core aluminum stranded wire. It is one of the key equipment in the power transmission and transformation system.

aluminum bus pipe in factory

Electrical aluminum bus tube pipe is a hollow tube structure with glossy surface, beautiful appearance and uniform size.

The outer diameter of Xienuo's tubular busbar ranges from φ60mm to φ450mm, the wall thickness ranges from 3mm to 12mm. The length of a single busbar can be up to 15 meters according to customer needs. Check out our available sizes.
