Electric cables for the mining industry

REGENT years have seen rapid development of rubberlike insulating and sheath materials for cable. The introduction of polychloroprene, commonly called neoprene, has provided a sheath material that is highly resistant to heat, flame, and abrasion. The availability of polychloroprene and heat- and ozone-resistant rubbers has influenced cable engineers to review cable practice in many fields, including mining, in the light of the improved safety and economy possible with such materials.
