Medium Voltage Power Cable Is Safe And Reliable Aug 07, 2017


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, Medium Voltage Power Cable power plants lead lines, industrial and mining enterprises within the power supply and across the river underwater transmission lines. In the power lines, Medium Voltage Power Cable 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.

The medium voltage power cable relates to the technical field of cable, Medium Voltage Power 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, 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; Medium Voltage Power Cable said conductor shielding layer, insulating layer and insulating shield layer are co-extruded and extruded on the conductor. The utility model has excellent performance such as flame retardant, Medium Voltage Power Cable 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. '

With the rapid development of modern life, the city, the rural power grid is also constantly updated to upgrade, the application of medium voltage power cable is getting higher and higher at the same time, the use of environmental diversity and application system diversification, making In this paper, the domestic medium-voltage cable in a rough summary of the summary, to facilitate the user in the course of the use of more accurate selection of cable varieties .1 medium voltage power cable voltage level, medium voltage power cable voltage level is divided into 3.6 / 6 kV, 6/6 kV, 6/10 kV, 8.7 / 10 kV, 8.7 / 15 kV, 12/20 kV, 18/30 kV, 21/35 kV and 26/35 kV, The production and performance requirements of the 6/10 kV, 8.7 / 10 kV and 8.7 / 15 kV cables are the same, but the power systems are not the same. The 6/6 kV and 8.7 / 10 kV cables are mainly used for safety Higher Class A, Class B systems, 6/10 kV and 8.7 / 15 kV cables are used in Class C systems where safety factors are low.
