Guide for selection and use of explosion-proof cable sealing joint

As the name suggests, the explosion-proof cable sealing joint can be applied to the environment with water to provide safe and reliable connector joints. The most important thing is to achieve the effect of waterproof. So how to select the type of explosion-proof cable sealing joint? What should we pay attention to in the process of installation and use?

Product introduction of explosion-proof cable sealing joint

The main body, nut and tightening head of plastic explosion-proof cable sealing joint are made of nylon PA66; Nylon pipe fittings are green and environment-friendly, without toxicity to human body and secondary pollution. They are suitable for long-term contact with water, without corrosion, toxicity and rust. The static working temperature is applicable to - 40 ℃ ~ 100 ℃, the instantaneous heat resistance can reach 120 ℃, the dynamic working temperature is - 20 ℃ ~ 80 ℃, and the instantaneous heat resistance can reach 100 ℃. Special clamping claw and rubber part design, large clamping cable range, strong tensile resistance, waterproof, dustproof, salt proof, acid and alkali resistant, alcohol, grease and general lubricants.

The sealing joint of metal explosion-proof cable is brass nickel plated, the clamping claw is nylon, and the clamping ring uses soft NBR to fasten the cable, so that the cable will not leave marks after removing the joint; It has good high temperature resistance, corrosion resistance and high pressure resistance, and the salt spray test shall not be less than 200 hours.

Installation and application scope:

Generally, one end of the thread is fixed on the shell, and the nut is tightened and fixed in the shell (or connected to the electric equipment with internal thread at the inlet and outlet according to the selection). The cable is directly led out from the waterproof joint, and the forcing nut is properly tightened, so that the cable can be protected.

It is widely used in the fixation and protection of wires and cables of mechanical equipment, electrical, marine electrical and anti-corrosion equipment.

Main function

Fastening and sealing of cables. Fastening refers to locking the cable through the waterproof joint, so that the cable will not produce axial displacement and radial rotation, so as to ensure the normal connection of the cable. Sealing means to isolate the entry of water and dust.
