Medium voltage power cable refers to 35,000 kv and below power cable.
Medium voltage power cable relates to cable technical field, including cable core, the filling layer and the outer sheath, the cable core consists of one or three insulated wire cores, Medium Voltage Power Cable and the insulating core consists of a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer and a metal shielding layer in turn, and is characterized in that The conductor shielding layer is composed of a half conductive conductor shielding rubber material; Medium Voltage Power Cable The insulating layer is composed of a medium pressure halogen-free ethylene-propylene rubber insulating material, wherein the insulating shielding layer is composed of a half conductive insulating shielding rubber material, and the conductor shielding layer, insulating layer and insulating shielding layer are packed on the conductor by Coextrusion. Medium Voltage Power Cable The utility model has excellent properties such as flame retardant, corrosion resistance, irradiation resistance, aging resistance and high dielectric property, and ensures its safe and reliable in the harsh use environment of the third generation nuclear power plant, Medium Voltage Power Cable and greatly improves the service life of the cable.
The voltage level of medium voltage power cable is divided into 3. $number kv, $number kv, $number kv, 8.7/10 kv, 8.7/15 kv, 12/20 kv, 18/30 kv, 21/35 kv and 26/35 kv. of which $number kv and $number kv, 8.7/10 KV and 8.7/15 KV Cable production process and performance requirements are the same, but the application of the power system is not the same. $number kv and 8.7/10 KV cable is mainly used in a Class A, Medium Voltage Power Cable B system with higher safety factor, $number kv and 8.7/15 KV cable is used in C class system with lower safety factor .
