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
