Heavy-Duty EPR/CPE Type G Portable Cable 2000V - Flame Retardant, Flat Parallel Design with Secure Grounding
Product Overview
The Type G Power Cable is a heavy-duty, flat parallel portable cable engineered for DC mining equipment and industrial applications requiring robust grounding and extreme durability. Rated for 2000 volts and 90°C, this cable combines EPR insulation, a CPE jacket, and a secure grounding system to deliver reliable power transmission in harsh, high-stress environments. Compliant with ICEA S-75-381 and MSHA flame-test standards, it ensures safety and performance in underground mines, quarries, and heavy machinery operations.
