Description

Technical Field

[0001] The utility model relates to the field of RVV wire and cable, and more specifically, to an RVV wire and cable with high temperature resistance, moisture resistance and anti-rat and ant properties. Background Art

[0002] The full name of RVV wire and cable is copper core polyvinyl chloride insulated and polyvinyl chloride sheathed flexible wire, which is mainly used for power supply wires, control wires and signal transmission wires for electrical appliances, instruments and electronic equipment and automation devices. Specifically, it can be used for anti-theft alarm systems, building intercom systems, etc.

[0003] After retrieval, the existing patent (publication number: 202022187050.9) discloses a wire and cable with high temperature resistance, including a heat insulation layer. A connecting plate is arranged on the outer wall of the heat insulation layer, an arc plate is arranged between two adjacent connecting plates, a protective layer is arranged on the outer side of the arc plate, a groove is formed in the arc plate, and a pore is formed between the arc plate and the protective layer. A strengthening layer is arranged in the heat insulation layer, and a winding belt is arranged in the strengthening layer. The beneficial effects are as follows: after the wire and cable is heated, the heat is effectively diffused through the pore and the groove, and then the heat is diffused out through the arc plate and the protective layer, so that the heat is diffused in time and effectively. Moreover, the heat insulation layer can block the external heat from entering the cable, ensuring the normal transmission of electricity.

[0004] The above cited patent document conducts high temperature resistance treatment on the wire and cable, but the RVV wire and cable does not have the function of aging resistance. When the RVV wire and cable is used in a humid or corrosive place, it is extremely easy to age seriously and be bitten by rats and ants, which is not convenient for users and reduces the practicability of the RVV wire and cable. And the conventional RVV generally has a maximum heat resistance of 70°C, which cannot meet the requirements of some places with high heat resistance. Moreover, when the RVV wire and cable is placed, it may be deformed under the influence of external equipment, resulting in a reduction in the service life of the RVV wire and cable.
