Medium Voltage Power Cable Service Life Jul 25, 2017


The medium voltage power cable relates to the technical field of cable, which comprises a cable core, a filling layer and an outer sheath, wherein the cable core is composed of one or three insulated core, which is composed of a conductor, a conductor A shielding layer, an insulating layer, Medium Voltage Power Cable an insulating shielding layer and a metal shielding layer, wherein the conductor shielding layer is composed of a semi-conductive conductor shielding rubber material; the insulating layer is composed of a medium pressure halogen-free ethylene propylene rubber insulation material ; Said insulating shield layer is composed of semi-conductive insulating shielding rubber material; said conductor shielding layer, insulating layer and insulating shield layer are co-extruded and extruded on the conductor. Medium Voltage Power Cable The utility model has excellent performance such as flame retardant, corrosion resistance, radiation resistance, aging resistance and high dielectricity, and is safe and reliable in the harsh use environment of the third generation nuclear power plant and greatly improves the service life of the cable.

Medium voltage power cable is 35 kV and below power cable.

Power cables can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (110 kV or more), high voltage cables (275 to 800 kV) and UHV cables (1000 kV and above) ).

Power cables are used to transmit and distribute electrical energy cables, power cables commonly used in urban underground power grids, power plants lead lines, Medium Voltage Power Cable industrial and mining enterprises within the power supply and across the river underwater transmission lines. In the power lines, the proportion of cable is gradually increasing.

The power cable is a cable product used to transmit and distribute high-power power in the main line of the power system, including various voltage classes of 1-500 kV and above, Medium Voltage Power Cable and various insulated power cables.

Medium and low voltage cables (generally 35KV and below): PVC insulated cables, polyethylene insulated cables, XLPE insulated cables. Medium voltage power cable is used to transmit and distribute power cable, power cable commonly used in urban underground power grid, power station leads lines, Medium Voltage Power Cable industrial and mining enterprises within the power supply and across the river water transmission line. In the power lines, the proportion of cable is gradually increasing. The power cable is a cable product used to transmit and distribute high-power power in the main line of the power system, including various voltage classes of 1-500 kV and above, and various insulated power cables.

Medium voltage power cables have different types, such as PVC insulated cables, polyethylene cables, etc., medium voltage cable voltage is below 35kv.
