Low-voltage power cable production method

Abstract

The invention discloses a low-voltage power cable production method, comprising the following steps: A, straightening the copper rod into a copper monofilament; B, coating the outer surface of the copper monofilament with an insulating layer to form insulated copper wires; C, stranding the plurality of insulated copper wires; D, coating the outer surface of the insulated copper wires after the stranding with an aluminum alloy belt to complete the armoring process to form a prefabricated cable; E, covering the outer surface of the prefabricated cable with a rubber protective cover; F, testing spark; G, inspecting the finished product; and H, packaging and storing into the warehouse. The low-voltage power cable made by the method provided by the invention effectively improves the overall strength thereof, and the rubber protective sleeve is composed of polytetrafluoroethylene, preservative, ultraviolet shielding agent, polyester fiber, polyvinyl chloride fiber, antioxidant, plasticizer,compound halogen-free flame retardant and antistatic agent, which may effectively improve the fireproof, anticorrosive and antistatic properties of the low-voltage power cable, and prolong the servicelife of the low-voltage power cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a production method of a low-voltage power cable. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the eighteenth century in human history. It has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. , it converts the primary energy of nature into electricity through mechanical energy devices, and then supplies electricity to various users through power transmissi...

Problems solved by technology

According to the voltage level, it can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (above 110 kV), extra high voltage cables (275 ~ 800 kV) and extra high voltage cables (1000 kV and above), In addition, it can also be divided into AC cables and DC cables according to the current system. Compared with low-voltage overhead lines and low-voltage overhead insulated lines, low-voltage power cables are more expensive and difficult to lay and maintain. Pole, does not occupy the ground, does not hinder the view, and is less affected by the outside world, and is widely used in low-voltage power distribution systems. However, the existing low-voltage power cables have poor overall strength, fire resistance, and corrosion resistance. To ensure its service life, we propose a low-voltage power cable production method
