How e-loop energy chain provides safe cable management for top drives

Written by: igus | Published:

Replacing conventional service loops for top drive systems on drilling rigs, the new e-loop energy chain provides safe cable management even in adverse weather conditions. The new modular system, which is made of high-performance plastic, ensures a defined minimum bend radius of the cables and provides strain relief.

In this week’s video, we see how the modular energy chain can be opened from the outside and filled at any time. This allows cables to be added or replaced quickly during maintenance. The links can also be changed easily. Multiple-secured screw connections are used between the chain links to prevent components from falling, thus increasing operational safety.

The chain links feature an impact-resistant outer body attachment made of PU foam and a cable-friendly interior made of high-performance igumid material. Both materials are corrosion-free and resistant to chemicals. In addition, the e-loop is constructed around a high-tensile plastic rope which absorbs the tensile strain of the cables. The rope consists of a synthetic plastic fibre, which is unbreakable, weather-resistant, flexible and corrosion-free. The e-loop can carry weights of up to 220kN with the rope.
