First, according to the standard specifications, the copper wire is twisted: a certain diameter and a certain number of bare copper wires are twisted into one strand by a machine. Wire into a cable: The twisted copper core is then wrapped with an insulating layer through a plastic extruder to form a core wire. Wire forming: Then according to customer needs, (such as two-core, three-core, multi-core power cord, etc.) twist several core wires together. Some require anti-interference, but also need to wrap aluminum foil and metal shielding net, and then pass the extrusion After the machine is wrapped with PVC sheath or other insulating materials, the wire is formed. Then comes to the plug department. Terminal: Strip one end of the wire to a certain length as needed, and then strip each core wire a little longer to expose the copper core. Insert the insert or the terminal bracket to rivet the copper core tightly. Injection plug: Connect the insert or On this end of the terminal bracket, use a mold to draw out the plug on the plastic beer machine. Tail treatment: According to the customer's request, you can peel off a section of the outer skin directly with the tail card, the tail plug, or without the tail plug, and then peel off each wire to expose the copper core for use. Wire inspection: The completed power cord needs to be inspected with an instrument to see if there is any disconnection or short circuit. The appearance is visually inspected by QC personnel for defective injection molding. After zui, it can be packaged and shipped.
There are many types of plug power cords we usually use, and there are also several kinds of insulation materials. The main ones are rubber wires, which are suitable for power devices with AC rated voltages of 300V/500V and 450/750V and below, household appliances, power tools, construction lighting, and machine interiors that require softness or movement. They are used as electricity: gas connection wires or wiring. PVC wire is mainly used for the internal connection of electronic and electrical equipment. Rubber is very soft, good elasticity, cold resistance, high temperature resistance, oil resistance, UV resistance, good flexibility, and high strength. This is not comparable to ordinary plastic threads.
The surface of the PVC line pipe is smooth, the fluid resistance is small, it is not scaled, and it is not suitable for the breeding of microorganisms. The coefficient of thermal expansion is small and does not shrink or deform. Rubber thread has certain weather resistance and certain oil resistance, can withstand greater mechanical external force, soft, good elasticity, cold resistance, ultraviolet resistance, good flexibility, high strength, PVC material is cheaper than rubber material.
