ACSR is a cable made of steel and aluminum wires stranded together. Aluminum conductors are lighter in weight than copper conductors for the same length and size. ACSR cables are widely used when laying overhead cables. Since the cable is completely suspended except for the ends, the weight of the cable must not be too heavy. Introduction of ACSR ACSR is called Aluminum Conductor Steel Reinforced , and according to the name, we can understand that the main materials of ACSR are aluminum and steel. Aerial cables are only supported by towers in the air, and with high wind speeds, the cables need to be well stabilized. The steel wire can effectively provide support for the cable. Aluminum conductors have poor electrical conductivity, but are only one-third the weight of copper, making it a very suitable conductor material for overhead cables. ACSR Construction ACSR cables have a simple construction and are bare conductors without insulation. An internal steel wire provides support and an ...

  A cable gland is also called a cable connector. Is an accessory in the cable connection for the connection between the cable and the device to ensure the tightness of the internal structure of the cable and the device at the connection. Any device that needs to be connected to a cable needs to use a cable cover to prevent water, dust, and foreign matter from entering the interior through the connection and causing a short circuit.   Structure of Cable Gland The cable gland is usually composed of an entry thread, cone, ring, secondary nut, outer seal, and sealing nut. In the structural design, a plurality of nuts are used to fix the cable and there are sealing rings to ensure the tightness of the connection, to prevent the long-term use of loose or external force caused by wear and fracture, affecting the correct connection of the equipment and cable resulting in equipment can not work normally.   The Role of The Cable Gland Cable gland is widely used in mechanical equip...

XLPE the abbreviation of crosslinked polyethylene, is polyethylene (PE) generated by a crosslinking reaction, greatly improves the performance of polyethylene, a network structure, this structure has a strong resistance to deformation at high temperatures. It has the physical and chemical characteristics of temperature and pressure resistance. PVC is a polymer produced by free radical polymerization of vinyl chloride monomer. The application range is very broad. What are the Advantages of XLPE and PVC？ Advantages of XLPE 1. XLPE has excellent electrical performance, and can effectively reduce the ground fault current.  2. Small bending radius, easy to lay compared with other cables of the same type.  3. It has good aging resistance, allowing XLPE cable to pass a large amount of current under normal operating temperature (90℃) and short circuit (250℃).  4. Good acid and alkali resistance, can withstand corrosive liquid or acid rain corrosion.  5. Has a strong creep re...
