Guangdong cable fault detection manufacturers can quickly find cable fault points Guangdong cable fault detection manufacturers can quickly find cable fault points, Shenzhen Noyafa Electronic Technology Co., Ltd. is a professional cable fault detection, emergency repair, and road inspection Guangdong cable fault detection manufacturers, Can quickly find cable faults Guangdong cable fault detection manufacturers can quickly find cable faults, Shenzhen Noyafa Electronic Technology Co., Ltd. is a professional organization engaged in cable fault detection, emergency repair, route search, fault location services, our company has been engaged in cable faults all the year round In actual work, such as fault detection, cable fault finding, cable fault location, high-voltage cable fault detection, etc., the cable insulation damage event triggered by the preventive test is habitually called cable breakdown. Such faults all occur under the DC test voltage, and the insulation damage is electrical breakdown, the grounding point is generally intact with lead wrap or copper skin, and there is no obvious external deformation (except mechanical trauma). The cable breakdown faults are mostly simple ground faults, the ground faults are relatively high, the fault point is dissected, and the insulating material has no carbonization point, but the aging structure of carbon holes and water branches can be found through the instrument.

For cable breakdown faults, especially some high-resistance grounding cable breakdown faults, the difficulty of testing is ranging. Because this type of fault is relatively hidden, the test parameters are complex and changeable, and there is a lack of regularity, the distance measurement is the key to whether the fault point of the cable can be found quickly.“High voltage loop method”,“Hammer method”Both have the most effective methods for detecting such faults.
