Problems solved by technology
[0002] Cable refers to the wire that conducts current. It is widely used in the fields of civil power transmission and power generation. In the cold northern regions, the requirements for cold resistance of cables are particularly high, because the temperature in the north is the lowest in winter, and there are often rainy and snowy weather. If the cable is not cold-resistant Otherwise, the power generation of the power plant cannot be guaranteed, and the household electricity consumption and factory electricity consumption of the people in the north cannot be guaranteed, which will bring inconvenience to the people and bring losses to the factory.

Embodiment Construction
[0009] Such as figure 1 As shown, a grounding control cold-resistant flame-retardant cable for power generation is composed of a grounding control cable core 1, a nitrile insulating layer 2, a nickel tape armoring layer 3, an aluminum alloy tape shielding layer 4, and a galvanized copper tape armoring layer. The grounding control cable core 1 is set in two groups, each group of grounding control cable core 1 is provided with two sets of aluminum alloy conductor cable cores 11, and the outside of the two groups of grounding control cable cores 1 is wrapped with a layer of nitrile Insulation layer 2, the nitrile insulation layer 2 is wrapped with a nickel tape armor layer 3, the nickel tape armor layer 3 is wrapped with an aluminum alloy tape shielding layer 4, and the aluminum alloy conductor cable core 11. Four groups of aluminum alloy conductor cores are arranged inside.
[0010] A group of aluminum conductor cores 7 and a copper metal hose 6 are also arranged inside the nit...

The invention discloses a ground control cold-resistant flame-retardant cable for electricity generation. The ground control cold-resistant flame-retardant cable is composed of ground control cable cores, a butyronitrile insulation layer, a nickel-strip armor layer, an aluminum-alloy-strip shielding layer and a zinc-plating copper-strip armor jacket layer. The ground control cable cores are divided to two sets, two sets of aluminum-alloy conductor cable cores are arranged in each set of the ground control cable cores, the butyronitrile insulation layer covers the two sets of the ground control cable cores, the nickel-strip armor layer wraps the butyronitrile insulation layer, and the aluminum-alloy-strip shielding layer wraps the nickel-strip armor layer. The ground control cold-resistant flame-retardant cable has the advantages of being low in installation and laying temperature, long in service life, good in electric conductivity, cold resistant, flame retardant, acid-alkali resistant, corrosion resistant, and oil resistant.
Description
technical field [0001] The invention belongs to the field of cables, in particular to a grounding control cold-resistant and flame-retardant cable for power generation. Background technique [0002] Cable refers to the wire that conducts current. It is widely used in the fields of civil power transmission and power generation. In the cold northern regions, the requirements for cold resistance of cables are particularly high, because the temperature in the north is the lowest in winter, and there are often rainy and snowy weather. If the cable is not cold-resistant If this is not the case, it will not be able to guarantee the power generation of the power plant, the household electricity consumption of the people in the north, and the electricity consumption of the factory, which will cause inconvenience to people and bring losses to the factory. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present i...
