Factors that can cause flat cable failure

Cables are different from other industrial products, manufacturers of its production process is very strict control, then the factory before the issue of manufacturers to control, after the factory cable once the problem is difficult to find. So the power cable of the various questions to analyze, understand about the safe operation of the wire and cable system, to prevent the occurrence of failures is very necessary, 1. Cable joint failure: cable joints is the weakest link in the cable line, by the direct fault of the personnel (poor construction) caused by the failure of the cable joints occur from time to time. Construction personnel in the process of making cable joints, if there is a joint crimping is not tight, heating is not sufficient and other reasons, will lead to the reduction of cable head insulation, thus causing accidents.2. Environment and temperature: the external environment and heat sources in which the cable is located can also cause the cable temperature is too high, the insulation breakdown, and even the explosion of the fire.3. External damage: by the analysis of the operation of the last few years, especially in the rapid economic development of the Shanghai Pudong, now a considerable number of cable failures are caused by mechanical damage. For example: cable laying and installation of non-standardized construction, easy to cause mechanical damage; in the direct burial of cables to engage in civil construction is also very easy to run the cable damage. Sometimes if the damage is not serious, it takes months or even years to cause damage to the part of the complete breakdown of the formation of faults, and sometimes serious damage may occur short-circuit faults, directly affecting the flat cable and the safe production of power units.4. Insulation dampness: this situation is also very common, usually occurs in direct burial or rows of pipes in the cable joints. For example: cable joints production is not qualified and in humid climatic conditions do joints, will make the joints into the water or mixed with water vapor, time in the electric field under the action of the formation of water twigs, and gradually damage the insulation strength of the cable and cause failures. 5. long-term overloading: overloading: overloading, due to the thermal effect of the current, the load current through the cable will inevitably lead to the conductor heat, at the same time, the skin effect of the electric charge as well as the steel armor of the At the same time, the skin effect of electric charge and the eddy current loss of steel armor, insulation medium loss will also produce additional heat, so that the cable temperature rises. Long-term overload operation, the high temperature will accelerate the aging of the insulation, so that the insulation is broken. Especially in the hot summer, the temperature of the cable rises often lead to the weak point of the cable insulation is the first to be broken, so in the summer, the cable failure is also particularly high.-6, on the Evergrande electronic products network platform related to the introduction and sales of products briefly: Evergrande electronic products network - a professional agent / production / sales of all kinds of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
