Text and image details
The HQC-12 type SF6 fully insulated, fully enclosed, compact ring network switchgear adopts a modular design, perfectly unifying fixed and flexible expansion to suit the requirements of end users or network nodes, while meeting the needs of various power distribution switchgears, ring network cabinets, and cable branch boxes.
This product uses an SF6 load switch, with a spring-energy storage operating mechanism and a quick-make, quick-break device. The tripping mechanism automatically stretches the spring to store energy during the closing operation, and is controlled by a tripping coil or HRC fuse to release the latch. The gas tank is made of stainless steel, using laser welding, completely sealed, with no leaks, and requires no sealing rings.
This product features a compact structure, safety and reliability, small footprint, long service life, and maintenance-free operation.

Operating Environmental Conditions
● Normal Environmental Conditions
The HQC-12 ring network cabinet generally operates/serves under normal conditions, conforming to DL/T593-1996. The specific limits are as follows:
Ambient Temperature | Temperature | Maximum Average Relative Humidity |
Highest Temperature | +60℃ | 24-hour measurement ≤95% |
Lowest Temperature | -40℃ | 1-month measurement ≤95% |
Without reducing the gas pressure during installation: | ||
Maximum Altitude | 4000m |
|
● Special Environmental Conditions
For special harsh operating environments that differ from normal environmental conditions, users must consult the manufacturer in advance.
For example: When electrical equipment is installed at an altitude of more than 4000m, the atmospheric pressure will decrease, and therefore, overpressure in the cabinet must also be eliminated.
