The threading tube (full name "insulated electrical conduit for construction") is a pipe used to protect cables and wires. Its main functions include:
Protect cables from mechanical damage and environmental corrosion
Prevent cables from external pressure, friction or chemical substances (such as acid, alkali, salt) erosion, especially suitable for high temperature, dusty, humid or vibrating environments.
The smooth surface design reduces fluid resistance, avoids scaling and microbial growth, and extends the life of the cable.
Fire retardant and safety protection
Made of flame retardant materials (such as PVC), it can effectively prevent the flames from spreading after the insulation layer of the wire catches fire, reducing the risk of fire.
In places with high fire risks such as hotels and shopping malls, threading tubes with higher flame retardant grades are required.
Easy to maintain and replace lines
The wiring through the tube forms a "live line", and the wires can be easily replaced during later maintenance or upgrades to avoid damaging the wall structure.
Directly burying the wire will accelerate the aging of the insulation layer and make maintenance difficult.
Insulation and heat dissipation function
The insulation performance prevents current leakage and ensures the safety of electricity use.
Alleviate the heating problem of wires, especially in high-power circuits.
Adapt to the needs of various scenarios
Choose different types according to the environment, such as threading tubes (humid environment), galvanized steel pipes (industrial high-strength requirements), aluminum alloy pipes (lightweight scenarios), etc.
Pressure-resistant and moisture-proof threading tubes are required in special occasions such as underground projects and transportation facilities.
