Qufu City Xingda Mining Machinery Co., Ltd. is specialized in producing the old cable repair equipment manufacturers, the company's cable pressure number, cable hot fill machine, cable winding machine, dryer, cable and other products have a national patent, cable detectors, demolition secant machine is ideal equipment for the cable repair. 
 I. Introduction and model description 
 Mine is a cable to use big, due to harsh environmental conditions, underground work, so the damage than in a larger variety of cable, in order to save money, reduce production costs, the mine is equipped with its own wire general maintenance team. However, due to restrictions on testing equipment and technology, in the repair of mechanized mining cable, the detection test is often unsatisfactory, and most of the cable insulation damage by the larger force breakdown method, the device is based on the existing structure does not destroy the cable Local cable premise, based on the detection, can simply and accurately detect the cable operation sites, and they both tested after the repair function, so is mine cable repair operations can be fully trusted tool. 
 Second, the equipment components 
 (1) DC high voltage power supply 1; (2) Cable Fault Locator 1; (3) cable breakdown point apparatus 1; 
 (4) Digital Capacitance Table 1; (5), indicating a breakpoint; 
 (6) cable routing apparatus 1; (7) 1 Digital Megohmmeter 
 1-5 is mainly used in cable plants, mining sector; 
 1-7 major units for the construction, maintenance departments, and large factories, mines and enterprises. 

 Third, the instrument performance 
 1, practical, easy to learn, the failure rate can be measured; 
 2, no special requirements on the working environment (power should be no leakage protection); 
 3, no special requirements on the nature of fault, whether it is high resistance or low resistance; 
 4, cable length, thickness, depth, whether the meter scale model and no special requirements; 
 5, crude measurement accuracy of ± 2 ‰ + 1 m; 
 6, the precision measurement accuracy ≤ 1-3 cm, that is, without error.
