1. Core advantages:

Rapid deployment: Factory pre-installation and commissioning, shortening the on-site construction period by more than 70%;

Full environment adaptation: IP43 protection grade, suitable for harsh environments with temperatures of -40°C to +50°C and humidity ≤95%;

Long life design: The service life of the main structure is ≥20 years, and the anti-corrosion performance is up to 40 years without rust.

2. Structural design

A. Cabin structure

• frame: High-quality carbon structural steel (yield strength ≥ 235MPa), welded chassis steel, overall earthquake resistance and deformation resistance；

• Top cover: 5% slope roof design + drip edge to prevent water and snow accumulation;

• Door: Outward opening door (net width ≥ 0.9m), equipped with "push-bar" emergency escape lock and pressure relief function (dedicated to battery compartment)。

B. Internal layout

• Partitioned compartments: Steel plates and flame-retardant partitions separate equipment areas, corridors, and cable areas;

• Cable channel：

  • Primary cable: Double-layer galvanized fireproof trough (Class A fire resistance)

  • Secondary cable: Metal shielding trough (anti-electromagnetic interference)；

• floor: 50mm insulation rubber sheet + bottom wiring interlayer (applicable to battery compartment)。

3. Safety and protection system

A. Fire and explosion prevention

• Battery compartment dedicated: pressure relief door lock linked to combustible gas detector, forced ventilation to prevent airflow short circuit；

• General requirements: Automatically cut off air conditioning/ventilation and start mechanical smoke exhaust in case of fire (in accordance with GB50016)。

B. Grounding and lightning protection

• The overall grounding device (including non-electrical parts) has a conspicuous grounding mark;

• The cable entrance adopts sealing rubber ring + fireproof sealing (GB23864-2009)。

C. Emergency measures

• Emergency escape door lock + sound and light exit indication;

• Explosion-proof lighting switch (battery compartment)

4. Installation and Operation and Maintenance

A. Transportation and installation

• During transportation, the cabinet should be equipped with a movable fixing frame to prevent displacement damage;

• The bottom of the cabin is equipped with a pre-set cable trench entry hole (≥600mm×600mm), and the cover is hinged and fixed。

B. Operation and maintenance requirements

• daily: Clean the dust screen and check the sealing strip (replace every 5 years);

• Maintenance：Corridor width ≥ 0.9m, lighting supports full cabin power off maintenance.
