چکیده

Ethylene-Propylene-Diene Monomer (EPDM) insulators are used as indoor and outdoor insulators for high and medium voltage applications. This paper presents detailed investigations of the electrical properties of EPDM cable terminations. The effects of different environmental conditions (Dry and Wet at different salinities) under the effects of various levels of the ultraviolet (UV) radiation on EPDM cable termination have been studied through this work. The effect of Silicon grease coating on the EPDM insulators is also studied at different environmental conditions in order to improve their performance.

Innovative approach to strata reinforcement in coal mines with reference to evaluation cable bolts shear strength

There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile strength, as this kind of test can be carried out in the field as well as in the laboratory. Onl...

Diagnosis of MV Oil Filled Cable Terminations with X-Ray Imaging and Infrared (IR) Thermography

A main purpose of doing a diagnostic in cable system including its accessories such as impregnated paper insulated oil filled cable termination is to predict failure before they occur. Those cable and accessories, which are about to fail, can be replaced, thereby reducing the incidence of electrical system failure, thus reducing the electricity outages. This paper presents the work carried out ...
