Wire and cable manufacturers talk about how to choose the appropriate wire and cable?

After beginning of autumn, the temperature drops, so when selecting wires and cables, choose cables that can withstand severe cold, just like how to choose suitable wires and cables, hoping to help you!

After the weather gets cold, we have to encounter rain and snow weather problems. When the wind and snow fall into the middle of the cable and the cable, the cable may rotate, because the stable relative density of the cable is different, and when the snow slowly solidifies to the ice surface, it will also crack actively. Can be coated from the wire and cable cold building coating, according to the heat insulation to achieve the effect of cold.

If the wire and cable pass through the insulating layer during use, it may be damaged by mechanical equipment. In addition, the transportation cable is severely squeezed, which will destroy the insulating layer and protective layer. The tensile force of the directly buried cable accumulated at the bottom is too large, causing damage to the insulating layer and possibly breaking the cable.

In addition, it may also be caused by unreasonable engineering construction, resulting in common faults of cable head and weak point in the middle, causing water to invade the internal structure of the cable, or damaging the inner and outer sheath of the cable, causing water to penetrate.

Wire and cable manufacturers: how to distinguish the quality of wire and cable?

Wire and cable, as an important medium of power transmission, is widely used in household appliances, weapons and equipment, lighting lines, electrical products and other aspects, the quality of its good and bad directly affect the quality of construction and customer life safety.

The copper conductor of wire and cable should be applied with high purity electrolytic copper, which is evenly balanced and glossy. Some manufacturing enterprises in order to obtain a huge profit application of recycled copper, or shoddy to reduce the total area of copper core, resulting in the conductor resistance of the wire is more serious than the standard, the conductor current carrying capacity is affected, the use of the conductor overtemperature, seriously affect the use of the wire, resulting in safety risks.

Second, part of the wire and cable insulation resistance and protective sheath material application of recycled particles, its tensile strength and tensile strength can not meet the application requirements. This kind of cable is easy to break in the whole process of pressure, resulting in the exposure of the energized conductor, resulting in short circuit and leakage charge and discharge.

When selecting wires and cables, do not choose cables with too low a price. The price of finished cables is unlikely to be less than the cost of market sales. Second, it is necessary to understand the relevant qualifications of manufacturing enterprises. The state has implemented 3C verification for electric wires and cables. Some commodities are subject to the supervision of production licenses. There is no quality guarantee for the commodities of uncertified companies. When purchasing electric wires, they should ask the supplier for the product inspection report as much as possible. The quality of electric wires and cables is unlikely to be distinguished by naked eyes. Only through inspection can they be distinguished whether they meet the standards.
