Wire and cable company describes the problems that need to be paid attention to when using cables

Wire and cable as the key components of the power engineering system, in use must be regularly maintained and maintained, which can ensure our own daily safety of electricity, at the same time can extend the use of wire and cable, cable in daily use need to pay attention to the problems:

Cable company: Cable in daily use need to pay attention to the problem

1. Natural weather: wire and cable in use should try to ensure that it is directly exposed in the hot sun or damaged by wind and rain. Due to the accumulation of wire and cable over time, the aging of wire sleeve will be accelerated and the use of wire and cable will be reduced.

2, appropriate temperature: the internal ecological environment and heat source of the cable will also cause the cable temperature is too high, cable sheath breakdown, resulting in explosion accident fire.

3, overload operation: wires and cables should avoid overload operation, mainly because of the thermal effect of the current, the load flow will eventually lead to the heating of the electric conductor, in addition to the skin effect of positive charge and the eddy current loss of steel armor, cable sheath dielectric loss will also produce additional heat value, so as to increase the temperature of the cable. During long-term load operation, too high ambient temperature will accelerate the aging of the cable sheath, and even the breakdown of the cable sheath.

4, external force damage: wire and cable if paved in the area of strong acid and alkali energy is very strong, it will generally lead to corrosion of wire and cable, steel protective layer due to long-term organic chemical corrosion or electrolytic corrosion, resulting in the failure of steel protective layer, cable sheath reduction, will also lead to common cable failures. Therefore, when laying wire and cable parts, the local soil layer must be analyzed.

Wire and cable company: the way to identify the quality of cable common sense

Carefully check the cable quotation table written above the comparison of specifications and models, to see if it is not the same industry, at the same time, the cable this product is usually in the outer packaging surface is a security phone, can call to see. To see whether there is a quality certification system book, qualification certificate is not the standard, to see whether there is the name of the enterprise, production, testing stamp, production date; See whether the wire is printed with registered trademarks, specifications, operating voltage, etc. Also look at the cross section of wire and cable copper wire, red copper color bright, mild color, or it is a relic.

Wire and cable company: wire and cable transportation and storage

1. During transportation, it is prohibited to drop the cable or cable tray at a high height, especially when the ambient temperature is relatively low (generally below 5℃). Throwing and dropping the cable will likely cause the insulation layer and wire sleeve to crack.

2. Try to ensure that the cable is stored and placed outdoors in the exposed way. The cable tray can not be placed.

Wire and cable company: Thank you for watching, my company has a variety of cables welcome you to consult.
