XSD Cable: Analysis of The Hazards of Unqualified Photovoltaic Cable

Photovoltaic cable is a large class of electrical products used to transmit power, transmit information and realize electromagnetic energy conversion. Cables play an important role in all economic activities and social life. It can be said that where people are, where there is production, transportation, all economic activities, the cable can not be separated from the cable, so the cable is good or bad directly affect our lives.

The main problems of substandard products are the structure of the sheath before aging, conductor size, conductor resistance, insulation and tensile strength. Consumers using such products are prone to the danger of leakage, electric shock and even fire. These inferior products have laid many hidden dangers in the normal operation of the power system. Next, XSD Cable analyzes the hazards of unqualified wires and cables for everyone:

1、After the single-phase grounding (short circuit) accident of the cable, the relay protection device does not act to cut off the fault, making the wire and cable overheat and causing the insulation layer to catch fire.

2、Aging before the sheath insulation tensile strength and elongation of qualified wire and cable. Aging before the tensile strength and elongation of the insulation sheath is not qualified, directly and greatly shorten the service life of the cable, and in the construction process or in the high temperature and long periods of energized environment, the insulator is prone to fracture, resulting in the conductor is exposed to electricity, there is a risk of electric short circuit.

3、The conductor resistance of substandard wire. Conductor resistance is mainly an important indicator to assess whether the conductor material and cross-section of wire and cable are in line. When the conductor resistance exceeds the standard, the loss of current through the line increases, the wire and cable heating intensifies. The main reason for the failure of the conductor resistance is that the company in order to reduce costs, accounting for 80% of the cost of raw materials, copper shrinkage, either to reduce the cross-sectional area of the conductor, or the use of recycled copper in too many impurities, resulting in serious conductor resistance of wire and cable. Over the limit, in addition to the use of the process is prone to fire, but also accelerate the aging of the insulation layer of the clad wire.

Well, said so much about the hazards of substandard photovoltaic cable you get it, but also want to know more related news and information on our company XSD Cable official website, the follow-up will also push you more related news and information.
