Products Description
For buyers of industrial and mining enterprises and residential communities, the low power factor of the power distribution system can easily lead to waste of energy consumption and fines, and reactive power compensation is the core requirement. The 400V Voltage Distribution Box launched by Kechang Electric has a built-in intelligent reactive power compensation module, which supports mixed compensation methods of co-compensation and sub-compensation. The compensation capacitor is made of self-healing metallized film material, and the switching adopts composite switches to avoid the impact of closing inrush current.It can automatically detect the power factor of the power grid, dynamically adjust the compensation capacity, increase the power factor to more than 0.95, effectively reduce line loss and transformer load, save considerable electricity bills for buyers, and avoid the risk of fines for non-compliance with the power factor.
Surge Protection & Lightning Resistance
Outdoor and high-rise power distribution scenes are vulnerable to lightning strikes and voltage surges, and the risk of equipment damage is high. Buyers attach importance to lightning protection capabilities. The product is equipped with SPD surge protection device (lightning protection level II), which can quickly absorb the surge current generated by lightning and operating overvoltage, clamp the overvoltage to a safe range, and protect the back-end precision equipment and lines. The internal circuit adopts flame-retardant insulated wires and anti-pull-off terminal blocks. After 1.2kV withstand voltage test, there is no breakdown, which can effectively resist instantaneous voltage shocks, adapt to outdoor street lights, high-rise residential buildings and other scenes that are susceptible to surges, and reduce equipment failure and maintenance costs.

Intelligent Reclosing & Fault Handling
Instantaneous line failure can easily lead to power outages and affect normal operations. The intelligent reclosing function is an important consideration for buyers. The product is equipped with an intelligent leakage recloser module, which can accurately distinguish between instantaneous faults and permanent faults. When an instantaneous fault occurs, the recloser automatically restores the power supply, and when a permanent fault occurs, the circuit is quickly cut off and the alarm is raised to reduce unnecessary power failure time. With the display of local status indicators and fault codes, buyers can quickly determine the type of fault, and the maintenance efficiency is increased by 50%, especially suitable for scenarios where the continuity of power supply is required such as agricultural network transformation and community power distribution.
The outdoor power distribution scene environment is complex, and humidity, dust, and low temperature are the main causes of equipment failure. Kechang optimizes the protection design of the box body, with a protection level of IP54. The box body is treated by pickling phosphating + electrostatic spraying process, which has excellent corrosion resistance and UV resistance, and can operate stably in an environment with a wide temperature range of -30℃ to 55℃ and a relative humidity of 95%. The cabinet door is equipped with rain-proof eaves and sealing strips, and the cable inlet is equipped with waterproof plugging parts to completely isolate the intrusion of rain and dust. There is no need to install additional protective sheds, which are suitable for outdoor and open-air installation and reduce the supporting cost of the project.
Modular Design & Expansion Convenience
It is difficult for buyers to accurately estimate the load requirements in the early stages of the project, and the flexibility of equipment expansion is essential.The product adopts a fully modular structure design, and the internal functions are divided into independent units such as power distribution circuits, compensation modules, and protection modules. The units are highly interchangeable, and the modules can be added directly when the load is expanded in the later stage, without the need to replace the box as a whole.The terminals are designed with standardized copper bars, clearly marked, and support two-way wiring before and after. There is no need to significantly disassemble the original lines during the expansion and transformation, shorten the construction cycle, reduce the investment in transformation, and adapt to the expansion needs of enterprises such as upgrading production capacity and increasing residents in the community.
Project acceptance and after-sales guarantee are the core concerns of buyers. Kechang Electric strictly follows IEC 60439-1 low-voltage equipment standard production. The products have passed CE, RoHS certification and domestic GB 7251 standard testing. Each equipment comes with a complete factory test report and quality inspection documents, which can be directly used for project acceptance.At the technical service level, it provides full-process support for on-site investigation, program customization, installation and commissioning guidance, and engineers are on-site to assist in system linkage commissioning. It promises a 3-year warranty for the whole machine and free replacement of core components. Regular inspection and maintenance training services can be provided later to completely solve the worries of buyers in the procurement and operation and maintenance of power distribution equipment.
