Compound submarine cable wear test system of optic fibre

Compound submarine cable wear test system of optic fibre relates to a cable wear test system. At present, the discovery of searching, the degree of wear law of the compound submarine cable fault signature of optic fibre is all very difficult. The utility model discloses an earth anchor, anchor, wire rope, tension sensor, wear element, vibration exciter, vibration sensor, hoist engine and the controller that links to each other with tension sensor, vibration sensor, vibration exciter, hoist engine, extra large cable both ends are fixed through anchor, wire rope, tension sensor and earth anchor respectively, and the hoist engine hangs the middle part of extra large cable through wire rope, and vibration exciter and vibration sensor locate the portion of hanging of extra large cable, and wear element is located the both sides of the portion of hanging of extra large cable, pull with seizing wire at sea cable middle part, can swing back and forth under the control of hoist engine. This technical scheme is simple,
