Professional Complete Set of Power Distribution Cabinet Customization and Engineering Supporting Services
We are deeply engaged in the industrial electrical field, focusing on the core business of customizing complete sets of power distribution cabinets. We provide new factory supporting services, old factory renovation and special scenario adaptation services. With precise customization, efficient delivery and reliable quality, we empower customers to achieve safe commissioning and cost reduction & efficiency improvement.
Core Business and Supporting Services
Focusing on full-scenario needs, we offer three core services: new factory construction supporting (power planning adaptation, power distribution cabinet customization, project node coordination, connecting architectural and new energy needs to assist in early commissioning); old factory power distribution renovation (old cabinet replacement, energy efficiency optimization, designed with "minimum downtime" to balance safety and economy); special scenario customization (deeply rooted in new energy, chemical industry and other fields, customizing power distribution cabinets with high and low temperature resistance, corrosion resistance and dust-free performance to adapt to extreme working conditions).
Core Advantages of Complete Set Cabinet Customization
We professionally manufacture a full range of products including high and low voltage switchgear components, distribution boxes and control boxes, which can be accurately adapted to industrial, commercial, municipal and special scenarios on demand. We support a minimum order quantity of 1 unit, achieve 30-day fast delivery relying on an efficient supply chain, and provide full-process product service support from scheme design to finished product delivery.
Quality and Service Commitments
We strictly control all links of production and factory commissioning to ensure stable operation of cabinets; establish a rapid response mechanism to fully connect with customer needs, and provide full-cycle services from consultation to delivery, ensuring worry-free cooperation.
With professional customization capabilities and efficient services, we strive to be your trustworthy industrial electrical equipment partner and help your projects land efficiently.
3 Phase Power Distribution Cabinet
Internal Structure:
The distribution box is equipped with high-quality, brand-name components for reliable power distribution and protection. It features a CHNT molded case circuit breaker (MCCB) as the main switch, offering robust overload and short-circuit protection for the entire system. The main breaker feeds power to three banks of miniature circuit breakers (MCBs), which provide individual control and protection for each branch circuit. All live conductors are clearly color-coded: yellow, green, and red for the three phases (A, B, C). A dedicated PE (protective earth) terminal bar and an N (neutral) terminal bar are provided for safe grounding and neutral connections, ensuring compliance with standard electrical codes.
Selling Points:
This distribution box is designed for safety, durability, and ease of use. The enclosure is made of high-quality steel with a powder-coated finish, providing excellent corrosion resistance and mechanical strength. All wiring is neatly organized and routed, minimizing clutter and simplifying maintenance. The box door is fitted with a rubber gasket for dust and water resistance, and an earthing strap connects the door to the main enclosure for added safety. The layout ensures even distribution of the three phases to prevent unbalanced loads, while clearly labeled terminals and color-coded wires reduce installation errors.
Application Scenarios:
This three-phase distribution box is suitable for a wide range of commercial and industrial applications. It is commonly used in factories, workshops, office buildings, shopping malls, and residential complexes to distribute power to lighting circuits, power outlets, and small machinery. It can also be deployed in construction sites, warehouses, and public facilities, providing a safe and organized solution for power distribution and circuit protection in environments that require reliable electrical infrastructure.
