Cable Jointing, Termination & Testing | SAIEE Training Academy JHB

CABLE JOINTING, TERMINATION and TESTING

Due to physical limits on cable lengths for manufacturing and packaging, joints in cables become inevitable, particularly in the context of the utility sector. The cables need to be also terminated at sending and receiving end equipment, a very wide variety of them, in utility as well as industry applications and this calls for appropriate cable termination accessories. Cable terminations and joints form the weakest link in any distribution system. Also, a failed joint in an underground distribution system is much more difficult to locate and repair compared to any similar problem in overhead distribution systems.

We will discuss the different types of cables, the properties of the insulation materials, installation, testing as well as fault location in this course by looking at the fundamental aspects involved in this workshop.
