Product Description

As a China manufacturer with various production patents, Kexun independently developed and produced KXRM6-12 Type Secondary distribution switchgear listed as a high-tech product in Zhejiang Province, which is widely used in 10kV/6K power distribution systems, and is the first choice switch product for various urban and rural users' power distribution systems.
Conditions of use
KXMR6-12 type Secondary distribution switchgear iis suitable for various environments such as high and low temperature (+40ºC~-40ºC), humidity, dust, salt pollution, mines and high altitude (1000m),Short-term immersion in water within 24 hours does not affect the use.
Note: If the altitude is higher, please indicate the specific altitude.

Product features
KXRM6-12 Secondary distribution switchgear uses SF6 gas as arc extinguishing and insulating medium.
The switchgear is fully sealed and insulated; Busbars, switches and live parts are completely enclosed in stainless steel shell.
The cavity is filled with 1.4bar SF6 gas, and the protection level reaches IP67: the whole switch device is completely unaffected by external environmental conditions, which can ensure the normal operation of the switch even in extreme cases such as short-term water immersion, and the product is maintenance-free for life.
The cabinet has a perfect "five-prevention" interlocking device, which completely eliminates the possible operation failures of personnel and equipment caused by human misoperation.
All cabinets have reliable safe pressure relief channels, which can ensure the personal safety of operators even in extreme cases.
The cabinet is divided into two types: fixed unit combination and expandable unit combination.
The size of the KXRM6-12 Secondary distribution switchgear is convenient to install, and it can be suitable for places with narrow space and poor environmental conditions.
The cabinet can be equipped with electric, remote control and monitoring devices according to different needs of users.

Technical parameter
Transformer and line protection
The KXRM6-12 Secondary distribution switchgear unit combine type provides two transformer protection modes, namely, the load switch fuse combination apparatus and the circuit breaker with relay protection.

1. Transformer protection is a combination of current-limiting high-voltage fuse and load switch. The fuse room will be installed behind a separate locked enclosure located in the front of the unit. The load switch uses a spring energy storage mechanism, which can be triggered by the fuse striker.
2. In order to facilitate the replacement of the fuse, the operating handle can be used to remove the end cover of the fuse chamber. The tripping mechanism of the fuse is pre-positioned, which ensures the waterproof performance of the whole system.

Optional accessories

Auxiliary contact
The harmony between sophistication and functionality finds its zenith in our High Voltage Network Ring Main Unit Switchgear. Every load switch and circuit breaker is enhanced with a 2NO+2NC indicating switch position, ensuring clarity at a glance. For an added layer of operational security, a parallel trip coil, adaptable for both AC and DC, can be seamlessly integrated into the transformer switch and circuit breaker. Precision is paramount, thus the low-voltage control component is artfully stationed behind the front panel for user-friendly access.
Voltage indication
Our capacitive voltage indicator serves as your vigilant sentinel, adeptly revealing whether the bushing is charged. Ingeniously, the accompanying socket facilitates nuclear phasing, blending safety with sophistication.
Short circuit and ground fault indicator
Simplifying fault detection, our cable switch module can be equipped with indicators for short circuit and grounding faults. This strategic inclusion streamlines fault location, empowering users with efficient resolution capabilities.
Electric operation
Experience the epitome of operational versatility with our standard manual operation mechanism, tailored for both cable switch units and transformer units. Elevate your operational experience by opting for an electric operating mechanism. Our suite of cable switches, vacuum circuit breakers, and grounding switches operate seamlessly from mechanisms discreetly positioned behind the front panel. Standard configuration allows for user operation via handle, while an optional motor operating mechanism augments your control. It should be noted, the grounding switch is solely manual, uniquely equipped to close fault current with unmatched precision.
Cabling
Our use of standard bushings adheres meticulously to DIN47636 specifications, exemplifying our commitment to excellence. Uniform in height, these bushings are safeguarded by a robust cable room cover plate. For enhanced safety, some plates are engineered to interlock with the grounding switch. Moreover, our innovative double cable room cover plates are available for those seeking dual cable incoming lines.
Pressure indicator
Our pressure indicator, epitomized by a precision pressure gauge, provides critical pressure data at a glance. Augmenting this feature, our system can include electrical contacts that signal pressure reduction, ensuring proactive maintenance and operational stability.
Key lock
Enhance your security with our robust key locks, available for circuit breakers, load switches, and grounding switches. For additional safety, a lock interlocking semi-shelter can be installed, providing tailored security solutions for all critical components.
Quencher
Our cutting-edge ring network units can be fortified with arc arresters, forging a protective barrier against internal arcing. These arresters automatically engage on the incoming bushing, compatible with D, De, and V modules, as well as all cable modules. Note, these must be ordered with the unit for seamless integration. The arc extinguisher's operation is clearly indicated, with all SF6 cabinet electrical contacts strategically connected to terminals behind the front panel.
