SF6-insulated pole-mounted load break switch for Distribution Networks-38kV
Key attributes
| Brand | ROCKWILL |
| Model NO. | SF6-insulated pole-mounted load break switch for Distribution Networks-38kV |
| Rated voltage | 38kV |
| Series | RPS |
Description
The RPS-38 is a 38kV-class SF6-insulated pole-mounted load break switch (switch-disconnector) designed for distribution automation systems. KEMA type-tested with a 3mm stainless steel sealed tank, it delivers maintenance-free operation across extreme environments (-45°C to +85°C). Available in manual, motorized, remote-controlled, and automatic sectionalizer configurations.
Key Features
- Construction: 3mm stainless steel tank with minimal welds and helium-leak verified sealing (≤0.1% annual SF6 leakage rate).
- Configurations: Manual, motorized, remote-controlled, and automatic sectionalizer variants.
- Switching Mechanism: Patented spiral spring mechanism with consistent switching speeds.
- User Interface: Light-reflecting position markers visible at ground level; operation counter and gas density gauge.
- Bushing Options: Porcelain, silicone rubber, or cable termination.
- Safety: Arc-resistant design; manual override capability.
