Energy chains are often used in the protection of electric wires and cables. There are quite a number of styles of energy chains. Briefly speaking, there are bridge-type, multi-bridge-type, fully-enclosed, semi-enclosed, small-sized, open-ended, S-shaped and universal energy chains. Among them, the fully-enclosed and semi-enclosed chains are the ones that people see and are relatively common on the market. So what's the difference between these two types of energy chains? Users can make a choice according to the usage environment.
Semi-enclosed energy chain: lts appearance is similar to that of the bridge-type energy chain. The only difference is that the support rods on the outside of the energy chain are in a fully enclosed style, which can well protect the built-in wire tubes. The support rods on the inside are the same as those of the bridge-type energy chain.
Fully-enclosed energy chain: just like the semi-enclosed energy chain, the support rods on the outside are in a fully enclosed style. And the inside is also equipped with fully enclosed support sheets like the outside, which can effectively protect the internal wires and tubes.
