Guozhiyun customized a complete set of power distribution cabinets for the villa project in Malaysia. In the design of power distribution for villas in Malaysia, we took into account the decentralized and seasonal characteristics of villa buildings and the three-phase power supply requirements for indoor villas. In Malaysia, the low-voltage power distribution system adopts a frequency of 50Hz±1% and a voltage standard of 415V/240V. These electrical parameters all follow the IEC standard. Therefore, when designing a power distribution cabinet for a villa project in Malaysia, the design of the power distribution cabinet needs to meet these requirements. Guozhiyun customized the design of 32 sub-distribution cabinets including the main distribution cabinet and the side branches according to these requirements. We specially designed the “rib connection method” for the main distribution cabinet. This connection method ensures the safety of the power distribution system, while also taking into account the convenience of installation and maintenance.
