Product Parameters

Performance characteristics

(1) Compact structure, small size, small footprint, and convenient module functional design, transportation and installation.

(2) The shell can be made of steel plate, composite plate, non-metal and other materials, which is strong, heat-insulating, dustproof, moisture-proof, and small animal-proof.

(3) factory prefabricated, all equipment in the factory once installation, commissioning qualified, truly realize the substation construction factory, shorten the design and manufacturing cycle.

(4) Adopt relative sealing, full insulation and full protection design.

(5) The protection performance is perfect, the operation is convenient, and the high and low pressure sides can be measured.

(6) the degree of automation is high, the whole station can be designed intelligently according to the needs, the protection system adopts the substation microcomputer integrated automation device, decentralized installation, can realize the "four remote", the relay protection function is complete, to meet the requirements of unattended.

(7) All doors of the box are equipped with lighting devices that automatically open and close with the door opening and closing.

(8) All doors of the box are opened outward, the opening angle is not less than 120 °, and there is a positioning device.
