Common faults in cable lines are mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating faults, etc. When the above-mentioned fault occurs on the line, the power supply of the faulty cable should be cut off, the fault point is fo... read more
How to detect commonly used wires and cables? 1. Electrical function detection Wires mainly include conductor DC resistance, insulation resistance, product voltage test and voltage test between insulated cores. Each item is very important. The conductor resistance directly reflects the electrical tr... read more
1. Power Cable The products are mainly used in the transmission of strong electric energy in the generation, distribution, transmission, transformation and power supply lines. The passing current is large (tens of amperes to thousands of amperes), and the voltage is high (220V to 500kV and above). 2... read more
1.Unshielded / shielded twisted pair-this is the type of cable used for many Ethernets. There are four pairs of wires in the cable. There is a very thick plastic partition that can isolate each pair of cables by cables. Each pair of wires is twisted, so there is no interference from other devices on... read more
1. Longer distance-Because of the low attenuation (signal loss) rate, the signal transmitted through the optical cable can be 50 times longer than the signal transmitted using copper wire, without the need for a signal repeater to maintain the signal over a long distance like copper wire What about ... read more
