These cables are crucial for distributing power over larger distances and ensuring stable, efficient electricity delivery to businesses, factories, and large residential areas. -
What are the typical construction materials of medium voltage power cables?
Medium voltage power cables are typically constructed with copper or aluminum conductors for excellent electrical conductivity. The insulation is commonly made of cross-linked polyethylene (XLPE) or EPR (ethylene propylene rubber) to provide enhanced thermal stability and electrical performance. The sheath or outer layer is made from PVC or PE (polyethylene), which provides mechanical protection and ensures weather resistance. These materials ensure that medium voltage cables can handle high power loads while remaining durable and safe in various environments. -
What are the advantages of using medium voltage power cables?
Medium voltage power cables offer several key advantages:
1. Higher power capacity: They can handle larger electrical loads than low voltage cables, making them ideal for industrial applications and long-distance distribution.
