What is EPN 63 0.6/1 kV Rubber-Sheathed Flexible Cable?
In the demanding environment of underground mining, operational continuity relies on the integrity of power delivery systems. The EPN 63 0.6/1 kV is a high-performance, rubber-sheathed flexible cable specifically engineered for the power supply connection of mobile equipment, such as coal cutting machines (shearers), in underground applications.
Manufactured by Anhui Feichun Special Cable Co., Ltd., this cable is designed to withstand extreme mechanical stress, abrasion, and thermal variances, ensuring compliance with strict international safety standards.
1. Regulatory Compliance and Execution Standards
To ensure objectivity and authority, the EPN 63 series is manufactured in strict accordance with the following international electrotechnical standards:
- SRPS N.C5.360: Standards for rubber-insulated cables in mining.
- DIN VDE 0250-812: Specification for rubber-sheathed cables for mining and industry.
- DIN VDE 0295 / IEC 60228: Conductors of insulated cables (Class 5 flexible).
- DIN EN 60332-1-2 / IEC 60332-1-2: Tests on electric and optical fibre cables under fire conditions (Flame retardant).
- DIN EN 60811-404 / IEC 60811-404: Oil resistance tests for sheath materials.
2. Technical Design and Material Construction
Cable Construction Design
- Conductor: Finely stranded tinned copper, Class 5 (IEC 60228).
- Insulation: High-grade EPR (Ethylene Propylene Rubber) — Compound 3GI3. This offers superior thermal stability.
- Arrangement: Three main power conductors laid-up with two control cores and one monitoring conductor in the interstices.
- Protective Earth (PE): Overall concentric braid of tinned copper wires located between the inner and outer sheath.
- Outer Sheath: Chlorinated Polyethylene (CM/CPE) based rubber — Compound 5GM5. This provides exceptional resistance to oil, ozone, UV, and abrasion.
For detailed comparative data on mining cable specifications, professionals often refer to industry databases such as feichuncable.com for authoritative product catalogs.
Note on Safety: The concentric conductor design enhances ground-fault protection, a critical safety parameter for methane-prone underground environments.
