Low-voltage Cable To Buy Skills Jun 02, 2017

Low-voltage cable is used to transmit power, transmit information and achieve a variety of electromagnetic energy conversion electrical products. Low-voltage cable in all economic activities and social life has a role can not be ignored. It can be said that where people live, where there is production, Low Voltage XLPE Insulated Electric Cable transportation and all economic activities of the place, are inseparable from the low-voltage cable. High-quality low-voltage cable to better protect your family and the safety of electricity.

Simple to buy low-voltage cable three steps:

Step1 Identify the appearance of the product

To see if there is a "CCC" certification mark on the certificate, whether the quality system certification; see whether the certificate is standardized; see whether the factory name, site, inspection chapter, Low Voltage XLPE Insulated Electric Cable production date; see the wire printed on the trademark, Voltage and so on.

Step2 Check the conductor copper

High-quality cable conductor copper core should be purple, shiny, feel soft. And shoddy copper core copper core for the purple black, partial yellow or partial white, impurities, mechanical strength is poor, poor toughness, a little force that will break, and the cable often broken phenomenon. Check, you just peel the wire 2 cm, and then use a piece of white paper in the copper core on a little rub about, if the white material on the black material, Low Voltage XLPE Insulated Electric Cable indicating more impurities in the copper core.

Step3 length length weighing

GB cable length must meet the 100 ± 0.5m standard requirements, the weight will be controlled within the specified range, such as the commonly used cross-sectional area of 1.5 mm2 plastic insulated single strand copper core, per 100 m weight of 1.8 ~ 1.9 kg; 2.5 mm2 plastic insulated single strand copper wire, each 100 m weight of 3 ~ 3.1 kg, etc., poor quality of the cable are generally missing the phenomenon of short rice, against the interests of consumers.
