How to avoid being trapped when buying household cables?

Cable is a relatively insignificant raw material in home decoration, but it is closely related to everyone’s daily life and involves the problem of safe power consumption in daily life. Therefore, when purchasing AAAC Cable, we should pay special attention to avoid buying fake and shoddy goods. Here is a detailed description of how to … Read more

How to measure the temperature of cable terminal tail contact?

The contact resistance of the tail wire contact of AAAC Cable terminal (especially outdoor, sometimes connected by copper aluminum two different metals) will increase under the influence of long-term load and fault current, which will lead to overheating. When the line fails, the fault current flows through the contact, which will burn the contact. Measuring … Read more

What is the content of periodic test for high voltage cable?

“Power cable operation regulation” stipulates that under the condition of not losing normal oil pressure, it is not necessary to conduct DC withstand voltage test regularly for high voltage oil filled AAAC Cable. As long as the oil pressure is normal and the dielectric loss and breakdown strength of oil are qualified, it can be … Read more

Why measure the surface temperature of the cable in operation?

The temperature of the cable is closely related to the load, but only checking the load can not ensure that the AAAC Cable is not overheated (1) the thermal resistance coefficient and side-by-side correction coefficient used in calculating the allowable ampacity of cables may be different from the actual situation. (2) when choosing cables to … Read more

Factors affecting insulation resistance of wires and cables

Small insulation resistance is often encountered in AAC Cable production, which is affected by many factors. In fact, there are four main factors that have a great influence on the coefficient of insulation resistance. 1、 The influence of temperature With the increase of temperature, the insulation resistance coefficient decreases. This is due to the increase … Read more
