The most common and cost-effective material for electric wire trunking is PVC. PVC cable trunking is designed primarily for use in industrial settings where cable ventilation is required. Electric cable trunking made of PVC is used to keep wiring systems neat and protect cables from damage.
Very-high-frequency (VHF) radio and telecommunication systems frequently use trunking. Trunking is also a network that handles many signals at the same time. Audio, video, control signals, and pictures can all be sent via trunking.
Cable trunking is a safe routing and shielding method for electrical cables and wires that prevents them from being damaged accidentally.
