Wire and cable manufacturers aging wire and cable
There are many kinds of wire and cable specifications, a wide range of applications, the use of voltage in 1kV and below, in the face of special occasions continue to derive new products, such as fire-resistant cables, flame retardant cables, low smoke zero halogen / low smoke low halogen cable , Anti-termite, rat-proof cable, oil/cold/temperature/wear resistant cable, medical/agricultural/mining cable, thin-walled wire, etc. Next, Xiao Bian introduced the causes of aging of wire and cable manufacturers and wire and cable.
Wire and cable manufacturer
1. Baosheng Cable
Baosheng's wire and cable products are widely used in major international and domestic projects. The establishment of the wire sales company aims to expand Baosteel's first-class technology, equipment, and management-quality electric wire products from professional fields to civilian and special fields. And manage the network of retail outlets, and gradually form a close strategic cooperation relationship with a group of equipment, vehicles, and electronics companies.
2, Luneng Taishan cable
Shandong Luneng Taishan Cable Co., Ltd. was established in March 1994, formerly known as Shandong Cable Electric Co., Ltd. Later it was renamed Shandong Luneng Taishan Cable Co., Ltd. in 1999.
3, multicolored - Jiangnan cable
Wuxi Jiangnan Cable Co., Ltd. was founded in the early 1980s by the former Wuxi Jiangnan Cable Co., Ltd. and was established through the reorganization of assets. After nearly 30 years of development, it has become a well-known large-scale cable enterprise in the country and was selected as "China's manufacturing industry for three consecutive years." "Top 500" was selected as the "Top 500 Asian Brands."
4, Yanggu cable
Yanggu cable production and operation of the technology-intensive, highly efficient national large-scale enterprises, the country's largest rubber cable production base. Now has assets of 3 billion yuan, under the jurisdiction of 7 branches, can produce 7 major categories of 800 kinds of more than 21000 kinds of specifications of wire and cable, the annual comprehensive production capacity of 5 billion yuan.
5, Panda wire
Panda Electric Wire was founded in 1947. Shanghai Plastic Wire Factory Co., Ltd., famous for producing “Panda†brand wire, is a professional enterprise producing various plastic insulated wires and cables. It is the oldest and most influential wire and cable industry in China’s electrical equipment industry. One of the largest professional factories.
Wire and cable aging causes
1, external damage. From the operation analysis of recent years, especially in the high-speed economic development of Haipu East, a considerable number of cable faults are caused by mechanical damage. For example, when the cable is laid and installed, the construction is not standardized and it is easy to cause mechanical damage. It is also very easy to damage the cable during operation by carrying out the civil works on the buried cable. l Sometimes if the damage is not serious, it will take several months or even years to cause complete breakdown of the damaged part to form a fault, and sometimes severe damage may lead to a short-circuit fault, directly affecting the safe production of cables and power units.
2, insulation damp. This situation is also very common, usually occurs in the cable joints in the direct burial or exhaust pipe. For example, if the cable joints are not qualified and joints are made under humid weather conditions, the joints will be filled with water or mixed with water vapor. For a long time, the water branches will form under the action of the electric field, which will gradually damage the insulation strength of the cables and cause failures.
3, chemical corrosion. Cables directly buried in areas with acid and alkali effects often cause cable armoring, lead sheathing, or outer sheathing corrosion. The protective layer is subject to long-term chemical or electrolytic corrosion, resulting in failure of the protective layer and reduced insulation. Cable failure. The corrosion of the cable in chemical units is quite serious
4, long-term overload operation. Overload operation, due to the thermal effect of the current, the load current will inevitably lead to conductor heating when passing through the cable. At the same time, the skin effect of the charge and the eddy current loss and dielectric loss of the steel crucible will also generate additional heat, thus increasing the temperature of the cable. During long-term overload operation, an excessively high temperature will accelerate the aging of the insulation so that the insulation is broken down. Especially in the hot summer season, the temperature rise of the cable often leads to the first breakdown of the weak cable insulation. Therefore, in the summer, the fault of the cable is particularly high.
5, cable connector failure. Cable joints are the weakest link in the cable route. Faults of cable joints caused by direct personnel faults (bad construction) occur frequently. In the process of making cable joints, if the joints of the joints are not tightly connected and the heating is insufficient, the insulation may be reduced, which may cause accidents.
Editor's summary: The reasons for the aging of wire and cable manufacturers and wire and cable are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
