Site condition

Some substations in Shouning, Fujian are severely infested with rats. The rats bite the outer insulating rubber of the wires, causing short circuits in some areas. The site environment is harsh, and combined with the actual situation of the technicians’ field investigations, Hangzhou Hengma proposed a comprehensive plugging treatment plan. Use BBS anti-condensation blocking materials, various plugging devices, fire-proof mud, fire-proof board and other cable and pipe blocking products for on-site construction. After a week of construction, breakthrough progress was made and the problem was solved from the root cause.

There is a problem

1. The original plugging of underground cable trenches is all using foam, rags and other debris for random landfill, so the plugging is not tightly sealed, causing small animals to enter and damage the cable.

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

3. The openings of the inlet and outlet holes are random and the same as those in public places, which may lead to rodent infestation.

Construction difficulties

1. Complicated working conditions and poor environmental conditions.

2. There are many incoming and outgoing lines, and the import and export are irregular.

3. The construction height is above 6m.

4. The required product specifications are different and the types are complex.

5. Rat infestation and serious water leakage.

Comprehensive treatment of various blocking products is adopted to achieve the "three preventions" effect of fire prevention, waterproofing and prevention of small animals.
