Abstract
A prototype flat three-conductor number 6 awg g-gc shuttle-car trailing cable has been fabricated in an shd configuration using a conductive-rubber shield material with volume resistivity of 32 ohm- cm. Resistances measured through the shield, between a penetrating object and the cable grounding conductor, are 1,000 ohms or less. The conductive rubber can be easily stripped from the insulated conductors, which is important for splicing. An shc splicing approach appears to be practical and effective. In-mine evaluation with high-sensitivity ground-fault relaying is recommended.
