Products Function
In 35kV gas-insulated switchgear (GIS) and ring main units (RMUs), unused internal cone sockets pose a risk to system integrity. Our Inner Cone Insulation Plug is the definitive solution to seal these openings. Constructed with high-purity EPDM rubber, the plug creates a hermetic seal that prevents the leakage of insulating gas (SF6 or alternatives) and blocks external contaminants such as dust, moisture, and salt.
Unlike makeshift sealing methods, this plug is a permanent, fixed component with no moving parts. This design philosophy eliminates potential failure points, ensuring decades of trouble-free operation even in harsh environments. The integrated stress cone geometry optimizes the electric field distribution, preventing corona discharge and ensuring the safety of your personnel and equipment.
Typical Applications
- 35kV Gas-Insulated Switchgear (GIS):
Securely seals unused internal cone interfaces in cable or busbar connection chambers, maintaining gas pressure and system integrity. - 35kV Ring Main Units (RMUs):
Acts as a critical spare part for modular RMUs, providing reliable dust protection and insulation for reserved plug-in sockets. - 35kV Compact Substations:
Ensures safe and sealed terminations in space-constrained prefabricated substations, preventing moisture and contaminant ingress. - 35kV Power Transformers:
Perfectly caps unused cable connection ends on transformer bushings, safeguarding the internal oil or gas compartments. - Other Internal Cone Equipment:
Fully compatible with various electrical apparatus utilizing CENELEC B internal cone plug-in technology.
FAQ
Q: What is the purpose of a 35kV inner cone insulation plug?
A: It is used to seal unused internal cone (plug-in) sockets on switchgear, transformers, or RMUs. It maintains the gas pressure and insulation level of the equipment while protecting against dust and moisture.
Q: Is this plug compatible with SF6 gas compartments?
A: Yes. Our plug is designed for "fully sealed" construction and is fully compatible with SF6, dry air, and nitrogen insulated equipment.
