On site conditions: Some substations in Shouning, Fujian are severely affected by rodents, which have bitten and damaged the outer insulation of the wires, causing short circuits in some areas. The on-site environment is harsh, and based on the actual situation of the technical personnel on-site investigation, Hangzhou Hengma proposed a comprehensive sealing and treatment plan. Select BBS anti condensation sealing materials, various sealing devices, fireproof mud, fireproof boards and other cable pipeline sealing products for on-site construction. After a week of construction, breakthrough progress has been made and the problem has been solved from the root. Existing problem 1. The original sealing of underground cable trench was arbitrarily filled with foam, rags and other sundries, so the sealing was not firm and sealed, resulting in small movements

Site conditions

Some substations in Shouning, Fujian are severely affected by rodents, which have bitten the outer insulation of wires and caused short circuits in some areas. The on-site environment is harsh, and based on the actual situation of the technical personnel on-site investigation, Hangzhou Hengma proposed a comprehensive sealing and treatment plan. Select BBS anti condensation sealing materials, various sealing devices, fireproof mud, fireproof boards and other cable pipeline sealing products for on-site construction. After a week of construction, breakthrough progress has been made and the problem has been solved from the root.

Existing problems

1. The original sealing of the underground cable trench was arbitrarily filled with foam, rags and other sundries, so the sealing was not secure, leading to small animals entering and damaging the cable.

2. The initial civil construction between pipelines was not carried out in accordance with high standards and strict requirements, resulting in serious water leakage.

3. The opening of the inlet and outlet holes is arbitrary and the same as in public places, leading to the occurrence of rat infestation.

Construction difficulties

1. The working conditions are complex and the environmental conditions are poor.

2. There are many inlet and outlet lines, and the inlet and outlet are irregular.

3. The construction height should be over 6m.

4. The required product specifications and models vary, and the types are complex.

5. Rat infestation and severe water leakage.
