ROCKWILL is a specialist SF6-free switchgear manufacturer. We design, engineer and type-test our own dry-air and solid-insulated medium-voltage panels in-house — replacing SF6 with zero-GWP insulation, and shipping to distributors, EPCs and utilities worldwide.
When you source from an SF6-free switchgear manufacturer, what matters is control — of quality, lead time, price and the engineering behind the product. ROCKWILL owns the full chain.
Metal-enclosure fabrication, vacuum-interrupter assembly, sealing and routine testing in our own facility — full control over quality, lead time and price.
Our R&D team designs dry-air and solid-insulated systems to IEC 62271 and custom-engineers panels to your one-line diagram.
Panels are type-tested to IEC 62271-200 with full test reports, CE documentation and FAT support for the toughest tenders.
We ship to distributors, EPCs and utilities worldwide with export packing, shipping documentation and responsive English support.
Private-label manufacturing under your brand — your nameplate, manuals, packaging and technical literature.
ISO 9001-driven production, 100% routine testing before dispatch, sealed vacuum parts designed for decades of service.
The SF6-free switchgear product range, built around dry-air and solid insulation with sealed vacuum interruption.
Breaker, feeder, metering and bus-tie panels, 630A–1250A, for distribution and industrial incomers.
Air and solid-insulated RMUs for secondary distribution — the SF6-free RMU range.
Drop-in panels for retiring SF6 boards.
The reasons buyers repeatedly work with a manufacturer like ROCKWILL for their SF6-free projects.

Equipped with current transformers and various sensors, this GIS integrates overcurrent, short-circuit, ground fault and overvoltage protection functions; it monitors real-time electrical parameters, automatically trips the circuit breaker and triggers protection actions once current or voltage abnormalities are detected to isolate faulty circuits and guarantee safe operation of the power system and equipment.
Solid-insulated eco-friendly switchgear is ideally suited for harsh operating conditions, including coastal high-humidity areas, dusty and oily environments, extremely cold regions, urban cores and ecological protection zones, as well as confined installation spaces. It effectively eliminates risks such as gas leakage and low-temperature liquefaction, while fully complying with stringent environmental protection policies.
Yes. The XGN features disconnectable vacuum circuit breakers using air as the primary insulating medium, providing a 100% SF₆-free environmentally friendly solution.
It adopts SF₆‑free pure‑air insulation. Most ratings support 10 000 overhaul‑free mechanical operations. Rated filling absolute pressure 200 kPa, minimum functional absolute pressure 180 kPa.
IEC 62271 type-test reports, CE documentation and factory acceptance support, aligned with tender requirements.
