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. Disadvantages of PVC Pipes: PVC (polyvinyl chloride) pipe is a type of piping often used in plumbing applications. Power cables are defined by voltage grade and nominal cross-sectional area. 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. The process of implementing a PVC coating on cables. Does not conduct electricity, making it an excellent material for electrical applications, e.g. 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. Nov 13, 2011 #1 Welcome to ElectriciansForums.net - The American Electrical Advice Forum PVC stands for polyvinyl chloride. Mainly above 6 square mm cables are called power cables but it depends upon the use of a cable. 1. It was the 1950s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing. Despite the many benefits of PVC pipes, this type of piping has several disadvantages associated with it. Go. Discuss s y cable advantages and disadvantages in the Commercial Electrical Advice area at ElectriciansForums.net. PVC is a surprisingly useful material, and is used in a wide variety of different manners in a number of diverse industries. XLPE cables can have a higher over-load capacity. Temperature. XLPE cable has high short circuit rating. 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. S. stumas-Reaction score 1. insulation sheathing for cables, especially when combined with its fire-retardant properties; PVC Disadvantages. Limited thermal capability, though additives can stabilize PVC at higher temperatures 1; 2; Next. It has lower dielectric and constant power factor which can result in saving of power. Next Last. PVC pipes are self-insulating and capable of handling very high-temperature water. Good dialectic strength. XLPE cable can withstand higher temperature (90°C) compared to PVC (70°C). XLPE cables are lighter in weight and smaller bend radius hence lower installation cost. Just because of cable are enclosed in a tube the circuit can be rewired ore altered as required and additional points added reasonably easily. Here this post gives some information about the advantages and disadvantages of the conduit wiring system to better understand this topic. Disadvantages of PVC insulation cable. It is a thermoplastic resin, which means it can be softened by heating, and is produced by a process known as polymerization. 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.
