3. …your final connection.www.minecableservices.ca Mine Cable Services Corporation. 1. Introduction

4. …your final connection.www.minecableservices.ca Mine Cable Services Corporation. Vulcanization: The ideal solution to repair a cable type SHD-GC is a repair that leaves the cable jacket and splice with the same properties and characteristics as previous to the repair. In this manner, the vulcanized cable repair is the best option, giving the splice better mechanical resistance, (traction and abrasion), resistance to water and humidity, resistance to extreme heat and cold outdoor temperature, resistance to oxidization caused by contact to oil and grease, and also resistance to flame.
