How to choose stainless steel cable glands?

In the world of electrical connections, the importance of stainless steel cable glands is self-evident. Recently, CHUANGDA has sorted out several key issues about stainless steel cable glands that have been widely concerned recently, and answered them in detail.

Which of the 304 and 316 stainless steel cable glands is the most suitable?

● 304 stainless steel is widely used in conventional environments. It has good corrosion resistance, can resist general oxidation corrosion, has good processability and is affordable. It is suitable for ordinary indoor electrical wiring and cable connections in non-strong corrosion areas of small factories, which can ensure safe and reliable connections.

● In harsh environments, such as seaside marine facilities and chemical strong acid and alkali areas, 316 stainless steel has outstanding advantages. It contains molybdenum elements, has strong resistance to strong corrosive media such as chloride ions, and can form a stable passivation film. Although the price is high, it can extend the life of the joint and reduce long-term maintenance costs and safety risks.

How to correctly choose the right size of Stainless Steel Cable Glands?

● The outer diameter of the cable is the key to selecting the size of the stainless steel cable gland. Manufacturers have selection guides, and corresponding connectors are selected according to the outer diameter of the cable to ensure smooth insertion, tight sealing, and dust, moisture and other impurities.
● However, the actual installation environment and space limitations must also be considered. In narrow spaces or special-shaped places, in addition to adapting to the outer diameter of the cable, the outer size and shape of the connector must also be considered. In small instruments and equipment, compact size and shape connectors should be selected, and the convenience of installation and disassembly should also be taken into account.

What are the IP protection levels of Stainless Steel Cable Glands, and how to ensure their protection performance?

● The IP protection level of stainless steel cable glands measures the protection performance. Common ones are IP65, IP67, IP68, etc.
● IP65 can prevent dust and withstand low-pressure water spray. Suitable for ordinary indoor and outdoor environments, such as industrial plants and outdoor distribution boxes.
● IP67 is dustproof and can be immersed in water for a short time. It is used for cable wiring in areas where flooding may occur, such as underground parking lots and equipment near pools.
● IP68 can work deep underwater for a long time and withstand strong water pressure. Used for underwater equipment, marine engineering, etc.
● To ensure the protective performance, the tightening torque should be strictly controlled during installation and the operation should be carried out according to the manufacturer's regulations, otherwise the seal will be affected or the joint will be damaged. Regular maintenance and inspection are also important. Check the seal, connection and surface conditions, and repair or replace them in time if there are any problems.

What are the special requirements for the application of Stainless Steel Cable Glands in different industries?

● The chemical industry has highly corrosive substances, and has high requirements for the corrosion resistance of stainless steel cable glands. In addition to selecting materials such as 316 stainless steel, additional protection is often required. For example, anti-corrosion coatings and special sealing materials such as fluororubber are used to prevent the penetration of chemical substances.

● In the rail transit industry, cable glands must withstand vibration, impact, fire and waterproof requirements. The design must have sufficient mechanical strength and toughness, high-quality materials and processes must be used for manufacturing, installation must follow standard specifications, special fixing and shock absorption measures must be adopted, and the material structure must be flame retardant.

● In the construction industry, stainless steel cable glands must take into account both beauty and durability. The appearance should match the architectural style. For high-end buildings, simple, beautiful and color-matched joints should be selected. In terms of durability, stainless steel with good weather resistance should be selected, combined with reasonable installation and maintenance to reduce the cost of maintenance and replacement.

By understanding these key issues, electrical engineers and industry practitioners can scientifically select, install and use stainless steel cable connectors to ensure efficient, safe and stable operation of electrical systems, laying a solid foundation for electrical connections for the development of various industries.
