Overview
Industrial power distribution design is a key aspect of overall industrial design. The industrial sector places greater emphasis on production continuity, reduced energy consumption costs, and improved intelligent manufacturing. The scientific and rational design of power supply and distribution systems significantly impacts the safe and stable operation of industrial enterprises. Power system failures lasting just a few cycles can cause widespread production equipment shutdowns. Improving the design of power supply and distribution systems and adapting to changes in production power loads can ensure high-quality operation for industrial enterprises.
Taikai is committed to the high-end industrial power distribution market, combining intelligent components and system platforms to meet engineering and technical needs. This not only achieves status monitoring but also enables self-diagnostic functions for electrical equipment, significantly reducing the incidence of power line accidents. This provides customers with reliable power supply and distribution assurance and improves production efficiency.
Main products used in industrial power distribution: Air Circuit Breaker (ACB), Moulded-case circuit-breaker (MCCB), automatic transfer switches, AC contactors, etc.
Main requirements for low-voltage electrical appliances in industrial power distribution: safety and reliability, excellent performance, energy saving and consumption reduction, and environmental protection.

TKDQ series automatic transfer switch
The TKDQ series dual-power automatic transfer switch is suitable for two-power supply systems with a rated voltage of AC400V, a frequency of 50Hz, and a rated working current of up to 1600A. It serves as a switching device between the normal power supply and the backup power supply. When one power supply fails, it automatically switches between the normal and backup power supplies to ensure the continuity of power supply to important equipment. At the same time, it can provide short-circuit and overload protection for the downstream load and cables. It is mainly used in industrial control, fire protection, banks, and other important places where power outages are not allowed. Compliant standards: |
