Cable Gland is the name for a cable tightening screw or cable connector. Cable nuts are applied to control cables in hazardous or harsh environments, and absorb sparks of flames, blocking contaminants such as dust, dirt, and liquids.

1. What are cable glands?

Cable glands are cable tightening screws, the other name is a cable connector. Cable glands play the role of connecting and fixing control cables on cable trays, and electrical cabinets to ensure that there is no ingress of water, dirt, or explosion-proof substances. Cable glands are made from materials such as Plastic, copper, Nickel plated copper, stainless steel, or aluminum.

Depending on the installation environment and the specificity of the manufacturing field, there are many types of the cable gland with corresponding characteristics. The cable gland has metric, PG, G, NPT...

2. Applications of cable glands

The cable gland is applied in environments with high temperatures and hazardous substances, often exposed to sparks or containing a lot of dirt and liquids. Cable tightening screws ensure that the effects of the outside environment cannot penetrate inside the cable tray or electrical cabinet.

Cable tightening screws prevent the cable from being twisted or stretched, helping to maintain a stable connection with continuous, uninterrupted performance. Fasteners are designed in many different sizes, designs, and materials. Environments for cable gland application are:

  • Factory and manufacturing machinery
  • Robot Factory
  • Factory under automation technology
  • Shipyard
  • Widely applied in railway technology and installation technology.
