With the increasing reliability of power supply requirements, timely detection of cable defects become the key. The traditional method currently used is to conduct DC voltage withstand test on the cable. This method can only find larger defects, which are difficult to find when the smaller defects are tested. Moreover, the DC voltage withstand test is very harmful to the cable itself and belongs to the high strength Destructive test. The PD oscillation test is through the system detection loop of the cable discharge current in the pulse signal analysis and calculation to achieve the internal cable partial discharge value detection and location determination. Through the use of this new technology, can accurately grasp the operation of cable lines, early detection of potential safety problems, to avoid failure and reduce the accident rate.
A recovery strap is designed to "recover" a vehicle from the ditch, mud, etc. Nylon recovery straps have loops on each end for ease of use. A Tow Strap should not be used to recover or "snatch" a vehicle that's stuck. Traditional vehicle tow straps are much less flexible and designed only to pull a load that freely moves. The strap's inability to stretch can't absorb energy, which increases the likelihood that it will break. The metal hooks on the ends can then come unhooked and launch through the air at high speeds, injuring bystanders or the vehicles. Using a tow strap with very little stretch is extremely unsafe.
