Overview

Application

Engineered for demanding mining environments, the Type 441 (Class 1) high-voltage flexible cable is designed for powering large, mobile, medium-voltage machinery. As a Class 1 cable, it features a thinner insulation and sheath compared to Class 2, resulting in a smaller overall diameter and reduced weight. This design optimization makes it uniquely suited for applications that prioritize efficient reeling, lighter weight, and flexibility while still operating at high voltages.

Applicable Standards

AS/NZS 2802:2000
AS/NZS 1125
AS/NZS 3808
AS/NZS 5000.1

Construction

3×Conductors: Flexible stranded tinned annealed copper conductor.

Insulation: EPR.
Insulation Screen: Semi-conductive elastomer.
Cradle Separator: Semi-conductive PCP.
Overall Core Screen: Semi-conductive PCP filling and covering.
3×Interstitial Earth Conductor: Semi-conductive PCP covered flexible stranded tinned copper conductor.
1×Central Extensible Pilot: EPR covered flexible stranded tinned copper conductor.
