What are the selection considerations for rubber cable metal jacket equipment?

I. Rubber cable metal jacket equipment selection considerations? Rubber cable using special tight pressure process and annealing treatment and other advanced technologies to manufacture high-tech new cable, electrical performance, safety performance and practical applications of the cost-effective rubber cable to replace the copper-core cable has a very clear advantage, rubber cable in the overall electrical performance, such as: service life, electrical conductivity, creep resistance, tensile strength and weight than the traditional copper-core cables have performed more outstanding. Under the condition of the same load capacity, the weight of the rubber cable is only 1/2 of the ordinary copper cable. aluminum alloy material price advantage is also very obvious, under the premise of meeting the same electrical performance, the engineering cost of rubber cable is lower than the cost of copper core cable. (1) Moisture barrier performance: the metal jacket must be free of defects such as holes, sand holes, inclusions and cracks to ensure good waterproofing, moisture barrier, sealing performance. (2) shielding performance: the metal sleeve must be able to meet the requirements of the system's electrical performance, with the structure of the electrical continuity, to ensure that the rated short-circuit current can be conducted. (3) Mechanical protection: the metal sleeve must be strong, shock-resistant, able to resist internal thermal expansion and external mechanical stress. (4) Long-term stability: the metal sleeve must have long-term operational stability to ensure the normal service life of the cable. (5) Economy: In addition to the above electrical-mechanical properties, should also take into account the economy of the equipment, choose a reasonable cost-effective.
