What Are Cable Trays? An assembly of units/sections with associated fittings that form a rigid structural system to securely fasten or support cables. Think of a roadway bridge that supports traffic. Cable Tray Systems must provide protection to life & property against
Installation of capacitor bank shall be carried out in accordance to project specifications and approved drawings and technical submittals etc. Installation will be carried out by skilled and suitably experienced electricians under supervision of highly competent site supervisors and engineers to ensure the
At the stage of receiving the cables at project site, inspect the protective covering on the cable for evidence of shipment damage. Leave the factory-applied protective cover in place until removal is absolutely necessary. Where possible, check the copper sheath for evidence
Insulator Definition: Electric insulators are substances through which electric current cannot pass easily like glass, mica, dry air and Bakelite etc. Similarly materials which resist the transfer of heat are called thermal insulators like wood, glass wool, rubber etc. The materials which
