Project Name: design and processing of high voltage ACSR Cable bridge Innovative ideas: there are three 10kv High-voltage incoming lines for 112201 fully mechanized coal mining face, which are laid from 11 panel substation to equipment train of working face. The high-voltage cable enters the rubber conveying chute section and is suspended along the coal … Read more
1、 Basic introduction of wire and cable Wire and cable: usually twisted by several wires or groups of wires [at least two in each group], similar to rope. Each group of wires is insulated from each other and twisted around the center of a wire. The whole wire is covered with a highly insulating covering … Read more
In order to ensure that the sheath insulation will not be damaged under the action of lightning overvoltage and switching overvoltage, the sheath protector should be used. The ball gap protector was used in the early stage, but its disadvantage was that its surface was burnt by power frequency afterflow after each action. This type … Read more
Corona discharge occurs in the air gap of indoor heat shrinkable, cold shrinkable or nylon AAC Cable terminal due to the action of electric field at the junction of semiconductor shielding layer and insulation layer of three core or single core cable. When the terminal position of the cable installed in the indoor switch cabinet … Read more
When multiple cables are running in parallel, load measurement shall be conducted regularly to understand the load distribution and correctly grasp the operation status of ACSR Cables. The load distribution of multiple cables is uneven when running in parallel, and even one phase load of one cable will be close to zero. The main reason … Read more

1、 Troubleshooting of common faults in injection molding of ACSR Cables Under note Fault analysis and Troubleshooting: (1) The temperature of the melt is too low. The forming temperature should be increased properly. (2) Forming cycle is too short. It should be extended appropriately. (3) Insufficient injection pressure. It should be improved appropriately. (4) The … Read more
Many friends may think that the thicker the AAC Cable, the better the insulation performance, the more durable the cable, and the better the quality. In fact, this idea is taken for granted, and there are some misunderstandings. This is because the insulation performance of cables depends on the technical indicators. The state has strict … Read more
High temperature wire and cable are everywhere in our life, and widely used, it brings a lot of convenience to our life, and high temperature wire and cable has many advantages compared with ordinary ACSR Cable. Today, Shanghai Qiyue high temperature cable editor will talk about some common sense problems of high temperature wire and … Read more
The environment of AAAC Cable laying is complex and diverse, such as bridge, direct burial, cable trench, pipe laying and so on. Therefore, when laying, operators often reserve a certain length in the planned length. There are many advantages in doing so. On the one hand, for the convenience of future maintenance, on the other … Read more
