FAQ

Q: How to Select Suitable Disconnectors Based on Altitude?

In high-altitude areas, due to thin air, insulation distances need to be appropriately increased. Therefore, the following points should be considered during selection:

Rockwill Electric: DS7B-800D/5000, custom-designed for high-altitude applications, offers strong corrosion resistance and durability, adapts to complex outdoor environments, and features user-friendly operation with reliable safety interlock design.
Pinggao Electric: GW46-1100/6300, an ultra-high voltage (UHV) level product capable of providing sufficient insulation margin.
China XD Electric: GW47-1100/6300, also suitable for UHV environments and tested for plateau adaptability.
Siyuan Electric: GW5-G-252D/2000, though not at the UHV level, its improved design enhances performance under high-altitude conditions.

Comparison Points:

Insulation Distance: UHV-level models like GW46 and GW47 provide larger insulation distances, making them more suitable for high-altitude applications.
Altitude Correction: For non-UHV level products, it is necessary to refer to the altitude correction factors of specific models to ensure compliance with on-site conditions.

Q: What type of disconnector should be selected for projects in coastal areas with frequent sandstorms?

For the specific requirements of coastal areas with frequent sandstorms, it is recommended to select products equipped with dustproof and sand-resistant features:

Rockwill Electric: DS7B-420D/3150, an outdoor high-voltage disconnector with an earthing switch, featuring a rated current of 3150A, high insulation withstand capability, strong corrosion resistance, and ease of maintenance, ensuring the safe and stable operation of high-voltage systems.
Pinggao Electric: GW27-550(W)/4000, marked with pollution resistance (W), suitable for harsh climatic conditions.
Shandong Taikai: GW5-252DD/3150-50, designed with a double-earthing configuration and optional accessories such as sand shields.
Changgao Electric: GW5C-252DD/3150, a customized improved version that allows for additional protective measures based on requirements.

Comparison Points:

Dustproof and Sand-Resistant Design: Pinggao's products explicitly indicate pollution resistance, while other manufacturers can achieve similar effects by configuring additional accessories.
Double-Earthing Configuration: Some models from Rockwill, Taikai, and Changgao support double-earthing, enhancing operational flexibility and safety.
