LIAONING DECHENG SCIENCE & TECHNOLOGY GROUP CO..LTD.
With Chlorinated Polyethylene (herein below called CPE) elastomer CM361M, blended with other additives and pigments, CPE Jacket has good properties of fire retardancy, oil-proof, wearing-proof, tearing-proof, good resistance to cold & weathering and excellent mechanical properties. Our DCH03C rubber-sheath Compound follows GB7594.5-87 standard, or SE4.
Rubber sheath made by CDH 03C is the first ideal substitution of CR & CSM because of its excellent properties, good extruded rubber surface and lower cost.
1. Mine cables distinguish its pressure's class according to their colors as per the regulation of GB12972-91 & MT818-1999 standard.
2. Our yellow and red DCH 03C compounds are suitable for 0.66/1.14kv & 3.6/6kv cable for mine purpose. They have bright color, permanent stability, smooth and flat surface, excellent mechanical properties and exceed traditional CR colored cable sheath far away.
