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