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
Definition of filling coefficient on AAAC Cable Manual: ratio of actual cross-sectional area of conductor to cross-sectional area of core outline Filling coefficient of circular core = sum of cross-sectional area of each single line / circumcircle area of stranded core Fan, pad core filling factor = sum of each single line cross-sectional area / … 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 main function of wire and cable is to transmit electric energy, signal and realize electromagnetic conversion. The transmission of electric power, such as power cable, overhead line, etc., is the same as shaft ABC Cable, and the wire with electromagnetic conversion is like paint wrapped wire. If you choose a wire or cable, you … 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
When the power cable passes through a certain load current, it will be heated. With the increase of load current, the higher the cable surface temperature is. If it is not managed in time, the consequences can be imagined. For example, PVC cable is considered with core temperature of 70 ℃ as the upper limit, … Read more
UL standard In UL standard, the common temperature resistance grades are 60 ℃, 70 ℃, 80 ℃, 90 ℃, 105 ℃, 125 ℃ and 150 ℃. How do these temperature ratings come? Is it the long-term operating temperature of the conductor? In fact, these so-called temperature ratings are called rating temperature in UL standards. It … Read more
The application of wire and cable in life is essential. What people pay more attention to is the quality of wires and cables, but the types of cables are also various. The more kinds, the more difficult it is to choose. Many people don’t know how to choose the right wires and cables to use, … Read more
In the field of wire drawing, the sliding water tank wire drawing machine is widely used, that is, there is a gap between the speed of the drum and the AAAC Cables, so that the wire can slip on the contact surface with the drum, resulting in sliding friction, which drives the wire to realize … Read more
