disadvantages of pvc cable

150 150

Over the many years of use of PVC, cable manufacturers have identified most compatibility problems and resolved them, however, there are always new building products coming onto the market. The price is relatively high, which is 2-5 times higher than that of ordinary flame-retardant cable.This is the same cross-section, but the mineral insulated cable has strong overload capability, so if it is the same current carrying capacity, the cross-section is reduced and the cost is reduced. PVC stands for polyvinyl chloride. 1. It is a thermoplastic resin, which means it can be softened by heating, and is produced by a process known as polymerization. Good dialectic strength. Mainly above 6 square mm cables are called power cables but it depends upon the use of a cable. XLPE cables can have a higher over-load capacity. It was the 1950s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing. Disadvantages of PVC Pipes: PVC (polyvinyl chloride) pipe is a type of piping often used in plumbing applications. It has lower dielectric and constant power factor which can result in saving of power. Next Last. insulation sheathing for cables, especially when combined with its fire-retardant properties; PVC Disadvantages. For PVC power cables we use IS:1554 and for XLPE power cables we use IS:7098 and for Rubber-based power cables, we use IS:9968 and other relevant specifications. Temperature. 1; 2; Next. Disadvantages of PVC insulation cable. 1) because there are a lot of chlorine, burning will emit a lot of smoke would be suffocating, affect the visibility and produce some carcinogenic substances and HCl gas, on the environment causing serious harm. S. stumas-Reaction score 1. The process of implementing a PVC coating on cables. Power cables are defined by voltage grade and nominal cross-sectional area. PVC is a surprisingly useful material, and is used in a wide variety of different manners in a number of diverse industries. XLPE cables are lighter in weight and smaller bend radius hence lower installation cost. PVC (Polyvinyl chloride) is widely used in electrical cable construction for insulation, bedding and sheathing. XLPE cable can withstand higher temperature (90°C) compared to PVC (70°C). Does not conduct electricity, making it an excellent material for electrical applications, e.g. Disadvantages of PVC insulation cable Date 2018-10-10 1) because there are a lot of chlorine, burning will emit a lot of smoke would be suffocating, affect the visibility and produce some carcinogenic substances and HCl gas, on the environment causing serious harm. Nov 13, 2011 #1 Welcome to ElectriciansForums.net - The American Electrical Advice Forum PVC pipes are self-insulating and capable of handling very high-temperature water. XLPE cable has high short circuit rating. Just because of cable are enclosed in a tube the circuit can be rewired ore altered as required and additional points added reasonably easily. Discuss s y cable advantages and disadvantages in the Commercial Electrical Advice area at ElectriciansForums.net.
