Q1: What is the difference between solid insulated switchgear and gas insulated switchgear?
A: Solid insulation uses epoxy resin integrated casting, with no gas leakage risk, is maintenance-free, and has good environmental friendliness; gas insulation relies on gas pressure and requires regular inspection.
Q2: Does epoxy resin insulation age? What is its lifespan?
A: High-quality epoxy resin with anti-aging additives is used, with a design life of over 30 years. Actual operation data shows insulation performance remains above 90% after 20 years of operation.
Q3: How is maintenance-free operation achieved?
A: Fully sealed structure isolates from the external environment, vacuum interrupter has long life, spring mechanism has maintenance-free lubrication, overall no need for regular overhaul.
Q4: Does it support intelligent upgrades?
A: Standard interfaces are reserved, allowing addition of intelligent monitoring modules including temperature monitoring, partial discharge monitoring, mechanical characteristic monitoring, etc.
Q5: Are installation requirements high?
A: Simple foundation requirements, no special foundation needed; modular design enables quick installation; detailed installation guidance and on-site technical support are provided.
