Installation is simple and not easy. This process was adapted from that used for celluloid and was really ill-fitted for PVC. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications. This article considers why it is important to ensure steel wire armour (swa) cables are effectively earthed. After, with the help of GI wires, the main PVC insulated cables are drawn through the conduit. Multi-compartment trunking is used where different electrical services are required in close proximity to each other. Very difficult to detect defects in wiring. Polyvinyl Chloride (PVC) is one of the most commonly used thermoplastic polymers in the world (next to only a few more widely used plastics like PET and PP). PVC conduit is the lightest in weight compared to other conduit materials, and usually lower in cost than other forms of conduit. PVC/Polyolefin Rubber Alloys - They have potential utility in many applications where conventional flexible vinyl compounds do not meet certain end-use performance requirements. It is very laborious to install. it is safe from corrosion (in case of PVC conduit) and risk of fire. Bronze alloy, which is suitable for coastal areas, chemical plants, oil refineries and underwater situations. Any roughness of cut and burrs should be removed with the aid of knife blade or simply by wiping with a cloth. The Standard was amended in 1967 to include non pressure products. 2.
