Cable glands and self-sealing grommets are usually designed for entering single or just a few cables. By utilising a gland plate, many cables with different diameters can be routed. Depending on the type, very high cable densities or ingress protection classes up to IP66/IP68 (according to IEC 60529) can be achieved.

A cable gland (more often known in the U.S. as a cord grip, cable strain relief, cable connector or cable fitting) is a device designed to attach and secure the end of ...
Cathodic shielding was first defined in the 1980s as being a problem, and technical papers on the subject have been regularly published since then. A 1999 report [69] concerning a 20,600 bbl (3,280 m 3) spill from a Saskatchewan crude oil line contains an excellent definition of the cathodic shielding problem:
Waterproofing conducted on the exterior of a freeway tunnel. Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.
Waterproof is defined by the ASTM as a treatment that resists the passage of water under pressure. [1] Generally, damp proofing keeps exterior moisture from entering a building; vapor barriers , a separate category, keep interior moisture from getting into walls.
Cable grommets. A cable grommet is a tube or ring through which an electrical cable passes. They are usually made of rubber or metal. [1]The grommet is usually inserted in holes in certain materials in order to protect, improve friction or seal cables passing through it, from a possible mechanical or chemical attack.
A cable protection system (CPS) protects subsea power cables against various factors that could reduce the cable's lifetime, when entering an offshore structure.. When a subsea power cable is laid, there is an area where the cable can be subjected to increased dynamic forces the cable is not necessarily designed to withstand over its lifetime.
