Waterproof cable glands are essential for safeguarding electrical systems from water, dust, and other environmental hazards. It is suitable for use in humid environments, and wet conditions and offers excellent resistance to temperature variations, high pressure, and corrosion. These features significantly expand its range of applications. As critical components in maintaining the safety and efficiency of electrical installations, selecting the correct cable gland with the right Ingress Protection (IP) rating is such an important thing. An in-depth overview of IP ratings is provided in this resource, along with practical guidance to help selecting the right waterproof cable gland for application, ensuring optimal performance and long-lasting durability.
Factors to consider when selecting waterproof cable glands:
-
IP rating (Ingress Protection ratings)
IP ratings are outlined by the international standard EN 60529. It specifies the level of protection provided by an enclosure against the entry of hazardous parts, solid objects, and water. These IP ratings are in two-digit numbers. The first digit indicates protection against particles, while the second digit represents protection against fluids.
An IP68 rating means the cable gland offers complete dust protection, as indicated by the “6,” ensuring it is dust-tight and preventing any particles from entering under normal conditions. The “8” signifies the gland’s ability to withstand extended submersion in water, providing protection even when submerged for long periods, under specified conditions.
IP Code Protection Against Solids Protection Against Liquids IP65 Dust tight Water jets IP66 Dust tight Powerful water jets IP67 Dust tight Immersion up to 1m IP68 Dust tight Long-term immersion - Along with IP ratings, there are other considerable factors like the size of the cable, the material of the cable gland, and the type of threads. Indian cable gland manufacturers provide a wide range of cable gland options to the customers to ensure a seal, proper strain relief, bespoke to the size of cable.
- It is important to clearly understand the use of thread specifications and screw thread standards. The most common thread specifications include Metric Thread, British Thread, American Thread, and German Thread (PG). Each of these cable gland global standards has unique characteristics suited to different applications, ensuring proper fit and performance in cable gland installations.
- When a model is being selected, the outer diameter of the cable can be matched to the bayonet size. Typically, the bayonet range and the cable’s outer diameter should differ by approximately 10%.
- Durable materials such as stainless steel, brass, or a combination are typically used to manufacture IP68 cable glands. Factors such as the application environment, corrosion resistance requirements, and specific industry standards influence the choice of material.
Common Industrial Applications of waterproof cable glands
- IP65-rated glands are well-suited for general outdoor use, offering protection against light water exposure and fine particles.
- IP66 glands deliver enhanced protection against high-pressure water streams and rough marine conditions, making them ideal for more challenging environments. These cable glands are designed to safeguard electrical cables installed outdoors, providing essential protection against rain and harsh weather conditions.
- IP67 glands are designed for short-term immersion, such as in cases of water pooling or brief inundation. These Cable glands are used to protect electronic equipment and cables from regular exposure to water. Mostly used in offshore applications.
- IP68 cable glands are the optimal choice, providing reliable performance when fully immersed in water for extended periods. IP68 cable glands find extensive application in outdoor installations, marine environments, underground setups, industrial settings, and situations where cables must be protected from dust and water. They offer excellent environmental sealing, making them ideal for situations involving submersion or exposure to extreme weather conditions.
- Metal cable glands are widely used in various applications, including mechanical equipment, marine electronics, and corrosion-resistant systems, where cable and wire protection is essential. They are particularly important in industries such as power plants, chemical plants, telecommunications network base stations, and marine vessels.
Additionally, they are commonly used in environments with high usage, such as sprinkler systems and street lighting.
