HDPE cable protection tube details description:

HDPE Pipes for Cable Protection is a pipe made of high-density polyethylene material, mainly used to protect power cables and communication cables. It has the characteristics of corrosion resistance, good electrical insulation, high toughness, long service life, etc. It is suitable for urban and rural power cable construction, traffic road and bridge, industrial park cable engineering and other occasions.

HDPE cable protection tube material characteristics and advantages:

Strong corrosion resistance: can resist acid, alkali, salt and other chemical substances erosion, suitable for a variety of harsh soil environment, such as chemical parks, coastal areas, can effectively extend the service life of the cable.
Good aging resistance: In the long-term use process, it is not easy to be affected by ultraviolet light, oxygen, moisture and other factors and aging, even in the outdoor long-term exposure, it can maintain good performance.
Good flexibility: It has high flexibility and impact resistance, can adapt to a certain degree of ground settlement or soil displacement, is not easy to break due to external force, and has a reliable protection effect on the cable. For example, in earthquake-prone areas or areas with unstable geological conditions, HDPE cable protection tubes can better cope with ground vibration and deformation.
Excellent insulation performance: As a cable protection tube, its own has good insulation performance, can effectively prevent cable leakage, short circuit and other faults, to ensure the safety of power transmission.
Smooth inner wall: the friction coefficient is small, the cable threading and laying process is smoother, reducing the wear of the cable skin, and also conducive to the subsequent maintenance and replacement of the cable.
Light weight: Compared with the traditional metal protective tube, the HDPE cable protective tube is lighter in weight, easy to handle, transport and construction installation, reducing labor intensity and construction costs.

HDPE Pipes for Cable Protection connection:

Hot melt connection: The hot melt machine is used to heat the connection part of the pipe and pipe fittings to a molten state, and then the two are quickly bonded, cooled and solidified under a certain pressure to form a solid connection. Suitable for the same material, nominal outer diameter ≥63mm pipe and pipe, pipe and pipe fittings connection.
Electric fusion connection: the electric fusion pipe is set on the pipe, and the resistance wire in the electric fusion pipe is electrified through the electric fusion welding machine, so that the resistance wire heats up and the contact surface of the pipe and the pipe is melted, and the body is formed after cooling. Suitable for various specifications of HDPE water pipe connection, especially suitable for nominal outer diameter < 63mm pipe or can not use hot melt connection occasions.
Socket connection: First heat one end of the HDPE pipe to soften it, and then insert the other end into the softening end, and then heat and apply pressure to make the two closely combined. This connection method is suitable for small-caliber HDPE pipes, convenient installation, fast connection speed, but the connection strength is slightly lower than that of hot melt butt and electric melt connection.
Joint connection: This joint has an internal cavity into which the PE pipe can be inserted, sealed and fixed by sealing rings or elastic clasp rings and other components, suitable for small and medium diameter PE pipe connection.
