These hazards of unqualified Guangxi wire cable
Wires cables are a large category of electrical products used to transmit electricity, transmit information realize electromagnetic energy conversion. During the random inspection process, a large number of substandard products were found. These inferior products have buried many hidden dangers for the normal operation of the power system.Guangxi cable manufacturer
1. Mark unqualified wires cables. Identification is the main way for wires cables to identify the basic information of products. According to the standard, the main contents of the logo are: product model, specification, standard number, factory name, origin, etc. within a certain logo interval. When the marking is unqualified, it will cause the construction personnel to make mistakes in the marking, may cause electrical accidents in serious cases.
2. Wires cables with unqualified structural dimensions. The main issue with the size of the structure is the thickness of the jacket the thickness of the insulation. When the sheath insulation thickness of Guangxi cables do meet the standard, the resistance strength of the wire cable will be seriously reduced, resulting in a shortened service life of the wire cable, in severe cases, the wire cable will be damaged. The cable may be damaged. Upon breakdown, the insulating (jacketing) layer fails to provide normal protection, resulting in electrical shorts fires.
3. Wire cable with qualified insulation tensile strength elongation before aging. The tensile strength elongation of the insulating sheath before aging are unqualified, which directly greatly shortens the service life of the wire cable, the insulating layer is easily broken during the construction process in a long-term power-on high-temperature environment, causing the conductor to be exposed to electricity electric shock. Danger of short circuit. The main reasons for its unqualified products are the use of recycled materials to reduce product costs, the second is the production of unqualified small enterprises.Guangxi wire cable
4. Wires with unqualified conductor resistance. Conductor resistance is mainly an important indicator to evaluate whether the conductor material cross-section of the wire cable are in compliance. When the conductor resistance exceeds the standard, the loss of the current passing through the line increases, the heating of the wire cable increases. The main reason for the unqualified conductor resistance is that in order to reduce the cost, the company will shrink the copper which accounts for 80% of the raw material cost. Either reduce the conductor cross-sectional area use regenerated copper with too high impurities, resulting in serious conductor resistance of the wire cable. Exceeding the standard will only cause fire during use, but also accelerate the aging of the insulating layer covering the wire.Guangxi cable
