Medium Voltage Electric Cables

Medium voltage cable is a power cable is most commonly used in the industries of commercial, industrial and electric. The prices of standard voltage for MV (medium voltage) cable between 5 KV and 35 KV, but this range can vary among manufacturers and standards. MV-90 and MV-105 cable, designed for up to 90°C and 105°C, respectively, are two of the most common call outs. Medium voltage cable is available in a wide range and you must learn its basic and common use before purchasing.

Medium voltage cable is available in single and multi-conductor with unshielded styles and flexible design for installation. Medium voltage cable is often designed with either ethylene-propylene rubber (EPR) or cross-linked polyethylene (XLPE). Some materials jacket commonly used in MV cables is polyvinyl chloride (PVC) and chlorinated polyethylene (CPE). Many popular popular mask shielding copper strips helically applied to the insulation.

Medium voltage cable is provided with two types of insulation, 100% or 133% levels. These levels allow the cable to better manage increased voltage system faults should occur. What is the insulation you choose depends on the time error compensation system level. If the fault clearing time is one minute or less, the cable insulation level of 100% is used. 100% is typically used in the system’s ground where there is only an increase of the minimum voltage. The insulation level of 133% is used when a fault is cleared in less than one hour, and it is commonly used in systems with high resistance grounded or ungrounded systems where voltage levels can rise from phase to phase .

Applications:

Medium voltage cable is generally used as a primary energy source for a variety of applications. If you set up these cables according to NEC standards then we can only use these wet or dry locations. It’s also known for their electrical stability and robust design, the medium voltage cables are in difficult applications such as pulp and paper, petrochemical plants, steel mills, textile mills, water and installations waste water, mining, railways and power plant utilities. MV cable is also approved for use in a pipe, open air, and direct burial underground conduits plateau.
