Main Features of Product
- DRM-24 series gas cabinet SF6 gas as arc extinguishing and insulation medium.
- Switch cabinet is fully sealed, fully insulated structure; Bus bars, switches and live parts are completely enclosed in stainless steel housing.
- The chamber is filled with 0.04Mpa SF6 gas, the protection level is up to IP67. The whole switch device is completely unaffected by the external environment, even in extreme cases such as short-term flooding can ensure the normal operation of the switch, and the product is maintenance-free for life.
- The switchgear has a perfect "five prevention" interlock device, which completely prevents personnel and equipment operation failures caused by human error.
- All switchgear has a reliable safe pressure relief channel, which can guarantee the personal safety of the operator even in extreme circumstances.
- Switchgear is divided into two categories: fixed unit combination and expandable unit combination.
- The switch cabinet usually enters and exits from the front, and can also realize side exit or side expansion according to different installation positions.
- The size of the cabinet is easy to install, and can be suitable for small space and poor environmental conditions.
- The switch cabinet can be configured with electric, remote control and monitoring devices according to different needs of users.
Flexible Outlet and Expansion Methods
All DRM-24 modules can be connected by side outlet and side expansion or side outlet and top expansion according to user requirements, which meets the needs of power supply schemes to the maximum extent.

Frequently Asked Questions
What is the protection level of the DRM-24 series switch cabinet?
The DRM-24 series switch cabinet has a protection level up to IP67. It features a fully sealed and fully insulated structure, ensuring the switchgear is completely unaffected by the external environment and can operate normally even during short-term flooding.
What gas is used in the DRM-24 series for insulation?
The DRM-24 series gas cabinet uses SF6 (sulfur hexafluoride) gas as the arc extinguishing and insulation medium, with an absolute pressure of 0.04Mpa at 20°C.
Under what environmental conditions can this switch cabinet operate?
It is suitable for high and low temperatures (+40°C to -40°C), wet, dusty, salt-polluted, mining, and high-altitude environments (less than 4000 meters). Short-term immersion in water within 24 hours does not affect its operation.
What standards does the DRM-24 series comply with?
It complies with international standards such as IEC60056, IEC60298, IEC60129, IEC60420, IEC60265, and IEC60694, as well as Chinese national standards including GB3804, GB3906, and GB11022.
How are the outlet and expansion methods configured?
All DRM-24 modules offer flexible configurations. They can be connected using side outlet with side expansion, or side outlet with top expansion, depending on the specific requirements of the user's power supply scheme.
