Product Advantages
- 1. The cabinets and partition boards adopting hot-dip Al-Zn alloy-coatedsteel sheet and frame adopting multiple bending technology make high overall intensity and good earth continuity.
- 2. Fully considering the operation characteristics of the neutral point of the power system without grounding or through the arc suppression coil grounding,increase the insulation clearance and enhance the insulation level, so as to ensure that the switchgear meets the high requirements for the insulation strength.
- 3. Completely metal clad and absolutely compartments separation.
The degrees of protection is IP4X，which effectively prevents the equipment from being invaded by sundries and insect pests. - 4. Simple and effective mechanical block for five- preventions, preventing from mis-operating.
The movable handcart use sworm and worm wheel propelling mechanism.The same type of handcart can be interchanged completely, easy to operate and maintain. - 5. lt can be installed away from the wall, which is more convenient for double sides maintenance. Or it can be installed against the wall maintain in front of the cabinet,with less space occupation.
- 6. width of panel is 550 mm, which can increase the utilization of distribution room
The product runs safely and reliably through the harsh condensation, filthand internal arc tolerance test.
Application Places
Suitable for AC 50HZ, rated working voltage 3-10KV, rated working current up to 3150A power distribution system, can be used as power generation, substations, factories, high-rise buildings and other places of power supply, power supply and large motor start, and loop control, protection and monitoring.
- Power Distribution in Industrial and Mining Enterprises: The KYN28A switchgear is used in industrial and mining enterprises for power distribution, ensuring efficient energy allocation within these operations.
- Electrical Infrastructure in High-rise Buildings: In high-rise buildings, the KYN28A switchgear plays a crucial role in the electrical infrastructure, providing a reliable system for power distribution.
- Substations and Power Plants: It is utilized in power plants and substations for the reception and distribution of electrical energy, serving as a key component in the power system.
