Ethylene propylene rubber insulated non-stick sheath electrical hand cable with 10kV rated voltage

Abstract

The present invention relates to a rated voltage 10kV ethylene-propylene rubber insulated and non-sticky sheathed power flexible cable, which includes a conductor, a semi-conductive nylon tape A is arranged outside the conductor, and a conductor shielding layer is provided between the semi-conductive nylon tape A and the rubber insulating layer , an insulating shielding layer is provided between the rubber insulating layer and B semiconducting nylon tape, an inner sheath is provided outside the insulating shielding layer through B semiconducting nylon tape and C semiconducting nylon tape, and a water blocking tape is provided outside the inner sheath There is an outer sheath, which is characterized in that there is a tinned annealed copper wire braided shielding layer between the B semi-conductive nylon tape and the C semi-conductive nylon tape, and a nylon wire braided shield is provided between the inner sheath and the water-blocking tape layer, and the outer sheath is a chlorosulfonated polyethylene rubber outer sheath mixed with melted polytetrafluoroethylene. The invention has the advantages of good flexibility and excellent waterproof and surface salt preventing properties of the sheath.

Description

technical field [0001] The present invention relates to a rated voltage 10kV ethylene propylene rubber insulated and non-sticky sheathed power flexible cable, in particular to a ternary ethylene propylene rubber insulated and non-sticky sheathed power flexible cable, which is especially suitable for inland lake areas with high salt content, such as Alashan in Inner Mongolia, Qinghai Lake, Yuncheng in Shanxi, Namtso in Tibet, etc., as well as the vast coastal areas of Shandong, Jiangsu, Fujian, Guangdong, Guangxi and Hainan, are used as power supply cables for salt production or salt chemical industry. It belongs to the technical field of cables. Background technique [0002] Salt is a very important chemical raw material and one of the necessities of people's life. my country has many inland lakes, a considerable part of which have high salt content, such as Xinjiang Salt Lake, Inner Mongolia Alxa, Qinghai Lake, Shanxi Yuncheng, Tibet Namtso Inland lakes, etc., plus my count...

[0002] Salt is a very important chemical raw material and one of the necessities of people's life. my country has many inland lakes, a considerable part of which have high salt content, such as Xinjiang Salt Lake, Inner Mongolia Alxa, Qinghai Lake, Shanxi Yuncheng, Tibet Namtso Inland lakes, etc., plus my country's extremely long coastline, such as Shandong in the Bohai Bay and coastal provinces and cities such as Jiangsu, Fujian, Guangdong, Guangxi and Hainan, there are many large-scale enterprises engaged in salt production or salt chemical industry, but they all have the same One problem: as a power supply cable for transmitting electric energy, because it is supported by buoys and laid above the lake or sea water, the surface of the cable is easy to accumulate salt, and the knot will become thicker, which not only increases the weight of the cable correspondingly, it is easy to corrode the cable, and Affect the heat dissipation of the cable, the final consequence can only reduce the current carrying capacity of the cable conductor and the service life of the cable, and in order not to increase the weight of the cable, the current cables are single-core
