❓ Technical Support & Frequently Asked Questions
What distinguishes EPR insulation from traditional rubber compounds?
▼
EPR (Ethylene Propylene Rubber) type 3GI3 offers superior electrical properties including enhanced dielectric strength, improved aging resistance, and excellent thermal stability. Unlike conventional rubber compounds, EPR maintains consistent performance across wide temperature ranges and provides better resistance to electrical treeing and partial discharge phenomena.
How does the spiral copper wire screening enhance performance?
▼
The spiral-wound tinned copper wire screen provides excellent electromagnetic interference (EMI) shielding while maintaining cable flexibility. This construction method ensures uniform current distribution during fault conditions, enhances mechanical protection of the insulation system, and provides a reliable earth path for safety and protection coordination.
What are the advantages of PCP sheath material?
▼
PCP (Polychloroprene) type 5GM3 sheath provides exceptional resistance to oils, acids, alkalis, and weathering conditions. It maintains flexibility at low temperatures while offering superior flame retardancy and mechanical protection. The material’s self-extinguishing properties make it ideal for critical electrical installations.
Can these cables be used in wet or underground environments?
▼
While primarily designed for dry switchgear applications, the NTMCWOEU’s PCP sheath provides good moisture resistance. For permanent underground installations, additional protective measures such as conduits or cable ducts are recommended. The cable’s construction meets IP54 environmental protection standards for temporary outdoor use.
What installation bend radius requirements apply?
▼
The Class 5 flexible conductor construction allows for tight bend radii during installation. Minimum bend radius during installation is 6 times the overall cable diameter, while stationary installation requires 4 times the diameter. This flexibility is particularly advantageous in confined switchgear compartments and mobile transformer connections.
