How do waterproof cable gland work?

The waterproof cable is composed of the body and nut, which can contain a separate O -shaped ring and sealed. Then assemble the cable glands in the round incision of the fence, capture the wall between the body and the nut, thereby forming a dense sealing water.

The biggest feature of the metal guards is that it has completely disappointment, so cables with metal sheaths have very good radial water resistance.

The marks on the waterproof cable are usually used to indicate the degree of waterproof protection of the waterproof cable, such as IP68, IP67, IP65.

The waterproof cable of waterproof cable is generally divided into two types: longitudinal water resistance and radial diameter water. Vertical water blocking this commonly used is water -resistant yarn, water -resistant powder and water blocking zone. Their water blocking mechanism is in these materials It contains a material that can expand water in water.
After entering, this material will expand quickly when the water will be expanded and prevent the water from spreading further along the cable.

In this way, the purpose of the cable is waterproof. Radial water resistance is mainly through squeeze HDPE Non -metal guards or hot pressure, welding, and cold pulp metal sheaths.
