2020-02-09

Two days ago, travelling to a substation in Jiangsu State Grid, after a field survey and research, deeply touched. Jiangsu is located in the lower reaches of the Yangtze River, mostly for the plains, the region's water network, rainfall is more groundwater is relatively rich, the impact of external infrastructure piling and pouring leads to the outdoor maintenance wells in the accumulation of water in the case of the worse, the accumulation of water through the PVC pipeline into the basement of the substation interior, a serious impact on the installation of electrical equipment within the substation, delaying the power delivery time. After the owner fully understood the waterproof effect of our company's inflatable cable duct sealing device, and after our survey gave a number of operational solutions, and finally timely replacement of the original traditional blocking mode (fire clay), the use of this new type of blocking products, a timely and effective solution to the problem of waterlogging, so that the substation electrical equipment can be installed smoothly. Nowadays, more and more State Grid projects use Hengma inflatable cable duct sealing device to replace the original pipe blocking material. Advantages of inflatable cable duct sealing: 1. fast installation, easy removal, not easy to damage the cable and pipeline; 2. low construction costs, without water, power support, without the need for traditional construction tools; 3. good sealing effect, effectively preventing the accumulation of water, sediment, insects and rodents, harmful gases and other substances into the pipeline; 4. not subject to acidic and alkaline environment, not subject to the influence of pipeline water flow; 5. flexible sealing can effectively solve the problem of heat expansion and cold shrinkage of the pipeline and the sealing material. Flexible plugging can effectively solve the problem of thermal expansion and contraction of pipe and plugging material, extend the time limit of waterproof sealing of pipe holes, and reduce the cost of late maintenance; 6. Spare empty pipe, single cable pipe holes, and multiple cable pipe holes can be installed; 7. Can withstand a small range of cable shifting, and has a certain degree of seismic capacity.

After the owner fully understood the waterproof effect of our company's inflatable cable duct sealing device, and after our survey gave a number of operational solutions, and finally timely replacement of the original traditional blocking mode (fire clay), the use of this new type of blocking products, a timely and effective solution to the problem of waterlogging, so that the substation electrical equipment can be installed smoothly.

Nowadays, more and more State Grid projects use Hengma inflatable cable duct sealing device to replace the original pipe blocking material. Advantages of inflatable cable duct sealing:

1. Quick installation, easy removal, not easy to damage cables and pipelines.

2. Low construction cost, no need for water, power support, no traditional construction tools.

3. Good sealing effect, effectively prevent water, sediment, insects and rodents, harmful gases and other substances into the pipeline.

4. Not affected by acidic and alkaline environment, not affected by pipeline water flow.

5. Flexible sealing can effectively solve the thermal expansion and contraction problem of pipeline and sealing material, prolong the time limit of waterproof sealing of pipe holes, and reduce the cost of late maintenance.

6. Spare empty pipe, single cable pipe hole, multiple cable pipe holes can be installed.

7. Can withstand a small range of cable displacement, with a certain degree of seismic capacity.
