Solid insulation ring network cabinet is a ring network cabinet with solid insulation material as the main insulation medium.

After the vacuum interrupter and its conductive connection, disconnector, grounding switch, main bus, branch bus and other main electric circuits are single or combined, they are encapsulated with solid insulation medium to one or several modules with certain functions, which can be combined or expanded again and have full insulation and full sealing performance. The accessible module surface is coated with conductive or semi conductive shielding layer and can be directly Ring network cabinet with reliable grounding.

Advantages and disadvantages editing

Compared with gas insulated ring network cabinet, it has its own advantages and disadvantages:

1) No risk of gas leakage and greenhouse effect, good environmental protection performance, maintenance free;

2) The whole sealed insulation structure of epoxy resin casting has reliable insulation performance and strong environmental adaptability;

3) Modular design, small size, flexible products, convenient for on-site assembly; for remote areas with poor road traffic conditions, it can be separated for transportation, and then assembled, so as to diversify the transportation and installation methods;

4) New products with high cost and incomplete supporting facilities;

5) The production technology is not mature and the rate of waste products is high;

6) Intelligent monitoring technology is not mature, and the effectiveness of detection results needs to be improved.
