    Product Functions

    This switchgear serves as a key component in medium-voltage distribution networks. Its core functions include the reliable receiving and distributing of electrical energy within designated grid sections. Furthermore, it provides essential protection for the network and connected equipment. A critical safety feature is its integrated "Five-Prevention" interlocking mechanism, which prevents misoperation to ensure personnel and equipment safety.

    Applicable Environment

    The equipment is designed for reliable operation under specific environmental conditions:

    ◇Ambient Temperature Range: -25°C to +40°C.

    ◇Installation Altitude: Not exceeding 1000 meters above sea level.

    ◇Humidity: Daily average relative humidity ≤95%; monthly average ≤90%.

    ◇The surrounding atmosphere must be free from explosive or corrosive gases, flammable vapors, conductive dust, or severe pollution.

    ◇The location should not be subject to severe vibration or pose fire/explosion hazards.

    Product Highlights

    ◆Dual Standard Compliance: Manufactured in accordance with both the Chinese national standard GB3906 and the international standard IEC298, guaranteeing wide acceptance and high-quality benchmarks.

    ◆Enhanced Safety: Equipped with a mandatory "Five-Prevention" interlocking system, significantly improving operational safety by preventing common electrical accidents.

    ◆Versatile Application: Excellently suited for diverse scenarios including three-phase AC ring main units, terminal distribution networks, and industrial power supply systems. Its compact design also allows for seamless installation in box-type substations.

    ◆Robust Construction: As a metal-enclosed, box-type fixed design, it offers strong protection, durability, and reliability for critical distribution functions in demanding utility and industrial environments.
