KYN28-12 switchgear cabinet is suitable for 3.6-12kV, three-phase AC 50Hz power distribution system, as a complete set of indoor power distribution device, which mainly accomplishes power receiving, distribution, control and protection, and can be adapted to the scenarios of high-voltage motor startup and secondary power transformation of the power grid. The cabinet adopts modular center-mounted structure, and the circuit breaker trolley is highly interchangeable, which can greatly reduce the difficulty of on-site operation and maintenance and improve the continuity of power supply.
The product strictly follows GB 3906, IEC 62271 and other domestic and international standards, adopts metal armored fully enclosed design, and the busbar room, circuit breaker room and cable room are independently separated, which can effectively inhibit the spread of fault arcs and ensure the safety of people and equipment. The protection level of the whole machine reaches IP4X, with excellent dustproof and anti-touch capability, adapting to various indoor industrial and electric power environments.
The cabinet is made of thickened cold-rolled steel plate with CNC machining and anti-corrosion plastic spraying process, which has high mechanical strength and long service life. Compatible with domestic VS1 and imported vacuum circuit breakers, supporting closed door operation and remote monitoring expansion, taking into account the safety, versatility and intelligent upgrading space, is the mainstream of the distribution network upgrading and transformation.

The products are designed and manufactured in strict accordance with GB 3906-2020, IEC 62271-200, DL/T 404 and other standards, and each of them has passed the factory test and type test, and we can provide third-party inspection reports and certificates of conformity.
The switchgear is made of ≥2mm high-quality zinc-aluminum-coated steel plate, which is processed by numerical control, acid-washing and phosphating, and electrostatic plastic spraying, with anticorrosion and wear-resisting and high mechanical strength, and it can be stably operated for more than 15 years under normal environment.
International transportation is by sea container/air transportation, the cabinet is reinforced with moisture-proof lamination and wooden frame, and supports various trade terms such as FOB and CIF.
Quasi-model regular orders 7-15 working days to ship; customized solutions 15-25 working days, batch large orders can be delivered in batches of expedited delivery, subject to contractual agreements.
The standard configuration is VS1 vacuum circuit breaker, cost-effective, convenient operation and maintenance; optional VD4 and other models, better breaking performance and mechanical life, according to the project budget and requirements of flexible matching.
Shell protection grade IP4X, compartment IP2X, suitable for indoor use, adapting to the dirt level Ⅱ environment, can be added with dehumidification heater to deal with high humidity places.
The after-sales service implements 24-hour round-the-clock response, and at the same time provides remote technical guidance to quickly solve equipment failure and minimize the loss of power outages.
It supports customization of size, circuit, secondary scheme, color, etc., and can realize multi-cabinet splicing and busbar extension according to the site requirements to meet the layout of different power distribution rooms.
Compared with the old fixed cabinets, it has the advantages of quick change of the center handcart, better five-prevention interlocking, safer isolation of compartments, more compact structure, more efficient operation and maintenance, and stronger intellectualized expandability.
