How to choose cable glands of different materials

Mar 06 , 25

Cable glands are key components in power systems, and their material selection directly affects the safe and stable operation of the power system.With so many cable glands on the market, here is a comprehensive guide to choosing the right material.

Cable gland material

Heat shrink material:It has the advantages of light weight, easy installation and low cost, but has low mechanical strength and average aging resistance. It is suitable for the connection of low-voltage and small-section cables.

Cold shrink material:It can shrink without heating, is easier to install, and has better sealing and aging resistance, but the cost is relatively high. It is suitable for the connection of medium and low voltage, small and medium cross-section cables.

Metal material:It has excellent mechanical strength and conductive properties, but is heavy, complex to install, and susceptible to corrosion. It is suitable for cable connections in special environments.

Selection Factors

Voltage level:Cables of different voltage levels have different requirements for insulation and electrical performance of connectors. Users should select appropriate connector materials according to the voltage level of the cable.

Usage Environment:Harsh environments such as outdoor, humid, and corrosive environments have higher requirements on the weather resistance, sealing, and corrosion resistance of cable connectors. Users should choose appropriate connector materials according to the use environment.

Cable cross section:The larger the cable cross-section, the higher the requirements for the mechanical strength and conductivity of the connector. Users should select the appropriate connector material based on the cable cross-section.

With the continuous development of new materials and new technologies, the materials of cable glands will also be continuously updated to provide users with more choices.

Nylon Anti-bending Cable Glands

Our Nylon Anti-bending Cable Glands is a high-performance sealing and fixation device designed to protect cable connections from environmental hazards such as dust, moisture, vibration, and mechanical stress. Made from durable nylon material, this cable gland combines lightweight construction with exceptional corrosion resistance, making it ideal for harsh industrial environments. Its integrated strain relief mechanism ensures secure cable retention, preventing pull-out and prolonging the lifespan of your electrical systems.

Nickel Plated Brass Blanking Plug

Nickel plated brass plugs are ductile and conductive. Nickel plating improves corrosion resistance, provides a smooth appearance and wear resistance. Used to keep out dust, dirt and moisture

Snap Bushing

The snap-on bushing is made of nylon 66, with high fire rating, oil and corrosion resistance. It is mainly used to plug the prepared holes on the housings of various cabinets, chassis, etc. It can be used as a preparation hole, or used to plug excess holes to maintain the appearance of the disk. To install, simply drill holes into the base plate and press the hole plugs in.
