1. Technical characteristics of low-voltage complete equipment
The overall design of low-voltage complete equipment is mature, with stable performance and strong engineering adaptability and operational safety. The equipment adopts high-quality cold-rolled steel plate cabinet, with strong structural rigidity, not easy to deform, high protection level, and excellent dust-proof, moisture-proof, and anti foreign object intrusion performance; The layout of internal components is reasonable, with clear zoning and orderly arrangement of busbars and circuits, effectively reducing temperature rise and avoiding phase to phase interference. Equipped with comprehensive electrical interlocking and safety protection design, it can effectively prevent misoperation and ensure high personal and equipment safety. The product has strong resistance to short-circuit impact, excellent dynamic and thermal stability performance, and can operate continuously at full load for a long time. It has low energy consumption, low noise, and low failure rate. Adopting a modular combination design, it is convenient for disassembly, maintenance, and expansion, and supports various installation methods such as floor mounted, wall mounted, and embedded, adapting to indoor conventional and diverse working environments.
