1. Electrical conductivity: the conductivity of aluminum alloy is 61.5% of copper IACS, and the current carrying capacity is 79% of copper, which is better than pure aluminum standard. 2. Creep resistance: the alloy material and annealing process of aluminum alloy conductor reduce the “creep” tendency of conductor under heating and pressure. Compared with pure […]

The operation quality, safety and reliability of power supply system are not only related to the quality of wires and cables, but also to the construction quality of cable accessories and lines. 1. Cable laying method The cable laying methods are as follows: directly buried laying, pipe laying, shallow trench laying, cable trench laying, cable […]

1. What should be paid attention to in the process of cable loading and unloading? Answer: In the process of transportation and loading and unloading, the power cables and cable trays shall not be damaged. It is strictly prohibited to push the cable trays directly from the vehicle. Cables should not be transported and stored […]

1. Why is it necessary to install a return line parallel to the cable in the single-core cable jacket earthing mode? Answer: In the cable line that is earthed at one end of metallic sheathing, to make sure the inductive voltage in protecting a jacket does not exceed permitted standard, must install the conductor that […]

Conductor material of power cable Copper conductor shall be used for power cables used in the following situations Motor excitation, important power supply, mobile electrical equipment, etc. should be connected with high reliability circuit Working environment such as vibration place, explosion risk or corrosion to aluminum; Fire resistant cable Close to high temperature equipment Crowded […]

With the continuous acceleration of social development, the demand for electricity is increasing day by day. With the advantage of high power supply reliability, power cables are more and more used in the transmission and distribution domains. At present, cross-linked polyethylene (“XLPE“) insulated power cables are safe and convenient, and easy to operate and maintain. […]

1. Cable shall be laid through pipes in the insulation wall: The wall is composed of weatherproof outer strong skin, insulation layer and wood with heat transfer coefficient of 10W/m2K or similar wood inner wall skin. The wire tube is fixed close to the inner wall, but not necessarily touched. Imagine that the heat of […]

ACSR conductor (Aluminum conductors steel-reinforced) Standards : IEC/ASTM/BS/NFC/CSA/EN Voltage: low/middle/high voltage Material : Aluminum Alloy 1350/Gi steel core Origin Place : China CONSTRUCTION: Aluminum 1350-H19 wires, concentrically stranded around a steel core. Core […]

1. The selection of cable sheath shall meet the following requirements: (1)For AC system single-core power cables, when it is necessary to enhance the resistance of the cable to external forces, a non-magnetic metal armor layer should be used. Effectively treated steel armor. (2) In a humid, chemically corrosive environment or easily immersed in water, […]

1.The selection of cable insulation type shall meet the following requirements: Under the operating voltage, operating current and its characteristics and environmental conditions, the cable insulation characteristics should not be less than the conventional expected service life. The selection should be based on factors such as operational reliability, ease of construction and maintenance, and comprehensive […]
