Aluminum Bare Transmission ACSR, AAC, AAC

Aluminum Bare Transmission cables are designed and manufactured for power distributions. Read More

Through primary and secondary power lines. These cables are installed through overhead distribution channels. Outdoor environment is very demanding thus Aluminum Bare Transmission Cables are made of resilient products and conductors which can withstand such conditions. Their conductors are made of 1350-H19 Aluminum series and insulated with the cross linked polyethylene or a high density polyethylene. Not all of these cables have an insulation layer, some are left bare. They include; ACSR, AAC and AAAC.

ACSR Standards and Approvals

ASTM B-230 Aluminum 1350-H19 wire for electrical purpose

ASTM B-232 Concentric laid Aluminum conductors

ASTM B-498 Zinc galvanized steel wire for electrical purpose

The solid central steel core is walled by one or more concentric strands of Aluminum alloy 1350 layers. Zinc coating protects the wire from corrosion.

AAC Standards and Approvals

ASTM B-230 Aluminum 1350-H19 wire

ASTM B-231 concentric lay stranded 1350 Aluminum conductors

1350 Aluminum series are helically wrapped round the central wire, whereby each layer has six strands more than the previous underlying layer.

AAAC Standards and Approvals

ASTM B-398 Aluminum alloy 6201-T81 conductors

ASTM B-399 concentric lay stranded 6201-T81

Bare Aluminum alloyed conductors of 6201 series are helically wrapped round the central wire

Features

Conductor

Aluminum 1350-H19 series conductors are soft and flexible hence easy to carry and install. Aluminum has a high electrical carrying capacity and this explains why it is a preferred choice for long distance power distribution. It is also lightweight as compared to heavy copper cables making it cost effective as it is not labour intensive.

Insulation

The high density polyethylene and cross linked polyethylene layers offers a superb chemical and mechanical protection to the cable, improving the service life and electrical conductivity. This layer also keeps the user safe from electric shocks. It is colour coded for easy identification.

Applications

These cables are used in primary and secondary overhead power distributions.
