Abstract: With the growth of Urban Cable industrialization rate year by year, the joint failures is also occur from time to time. When a fault occurs in the cable tunnel, the method of installing two cable joints is usually adopted for recovery, and the recovery time is long. Three quick repair cable joints were designed and improved.The cable joint (type A) has the advantages of fast cable recovery speed and short time,cable joint (type B) can be used for narrow cable tunnel, and the cable joint (type C) can be used for the condition that the cable length is not enough.There is no need to install two sets of cable joints,and the traditional cable joint can be replaced by pouring curable insulating agent.
