The main items of wire and cable products related indicators finished cable voltage, insulation resistance, insulation thickness, conductor DC resistance: GB required actually measured value must be less than the specified value. This failure will result in the transmission of electrical energy conductor generates heat in the process, especially in the high power it will work under overload state or the conductors overheat, the transmission power decreased bv wire, affect the conductivity or fire performance. Tensile strength and fracture elongation rate insulation before and after aging: tensile strength is too small, in the installation, once subject to certain external wires and cables, its insulation is prone to cracks and even rupture, causing a decline in safety performance wire and cable, for constitute crimes against persons and property. Mark examination: should be printed on the wire and cable manufacturer name, model specifications Yan'an bv wire, the voltage level of continuity flag. These are the user to select wire and cable products based on the well-being bv wire, such as voltage rating does not match, you can not determine if it will use the occasion when the user selects. The development trend of plastic wire and cable electrical equipment with plastic wire and cable is necessary to raise a variety of wire and cable equipment for the long-term allowable working temperature, development and production of high-temperature and high-temperature resistant, resistant to ultra-low temperature resistance, the special environment of products to meet different occasions needs; second is to improve the shielding properties of the cable, to meet the information transmission, automated systems, computer networks need; three is the development of a variety of fire-retardant, fire-resistant, environmentally friendly wire and cable industries to meet increased security requirements; Fourth wire and cable constructions compact, lightweight (small diameter and thin wall). Prefabrication (fixed length, with connectors, bunched supply). Huxian bv wire, the Middle East and cable, power cable Gold (Certified), bv wire supplied by Cable Co., Ltd. Shaanxi Baoli. Shaanxi Baoli Cable Co. (www.jinlidl.com) is Xi'an, power cables leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the cable, power cable leading gold Middle East with the staff warmly welcome all inquiries negotiations to create the Middle East cables, power cables gold a better future.
