What Is a Double Compression Cable Gland
A Double Compression Cable Gland is a cable entry device that provides compression at two points of the cable gland. This double compression helps create a strong grip around the cable and provides better sealing. It is commonly used with armoured cables where strong cable retention and environmental protection are required. The gland helps prevent the cable from moving or pulling away from the equipment while also creating a secure seal around the cable entry point.
The gland generally consists of components such as a gland body, locknut, compression ring, sealing ring, and other supporting parts. When the gland is properly installed, it holds the cable securely and helps prevent the entry of dust, water, and other unwanted materials. The double compression design makes these glands suitable for applications where cables need additional mechanical support and environmental protection.
