Application:
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.
Construction:
3×Conductors: Flexible stranded tinned annealed copper conductor.
Conductor Screen: Semi-conductive compound (for cables having a voltage rating of 3.3/3.3kV and above).
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.
