Wiring Package Module

Wire Package Module: The wiring package module contains material used to wire the complete elevator package. The wiring package consists of standard electrical components such as duct, junction boxes, conduit, and fittings. The wiring package also consists of wire that is unique to elevators. A traveling cable is an electrical "cable" consisting of numerous conductors that electrically connect the moving car to the elevator controller in the machine room. The traveling cable is an “engineered” cable designed and manufactured to prevent twisting as the elevator moves through the hoistway. The cable is also designed to be strong enough to withstand the constant movement. The cable is composed of electrical conductors to allow control signals, electricity for lighting, fans and utility outlets. The cable also includes shielded pairs for communication devices such as telephones.
