These insulators are used for the transmission and distribution of electric power at voltages up to 33 kV. A single-pin insulator is deployed to transmit voltages up to 11 kV but higher voltages require two-, three- or four-piece pin insulators
For connection of Cable to Switchgear Terminal, Transformer Terminal, Poles etc. termination kits are required. … Termination can be for XLPE & strong PILC Cable and can be used in extreme hazardous atmosphere conditions.
Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. If Cable Lugs of only copper or aluminum are used , a galvanic action occurs due to dissimilar contact. The use of bimetallic lugs thus ensures a technically sound and durable joint.
When suspension string is used to sustain extraordinary tensile load of conductor it is referred as string insulator. When there is a dead end or there is a sharp corner in transmission line, the line has to sustain a great tensile load of conductor or strain.
Ground rods can be made with many different materials, but copper is the most common materials used for residential installations. Ground rods are very good conductors of electricity and allow any dangerous electricity to flow to ground, taking the danger away from you and the electrical panel.
