Low-Voltage Power Distribution Control Cabine Integrated Sewage Treatment Equipment(ISTP)
IEC 61439 and GB 7251 Standards Compliant Power Distribution Cabinet
,Modular & Expandable Architecture Control Cabinet
,Safety-First Design Low-Voltage Power Distribution Control Cabinet
Product Overview
The Low-Voltage Power Distribution Control Cabinet is a flagship product from ZhongQiao Enlightenment, engineered for industrial and utility power distribution, fully compliant with IEC 61439 and GB 7251 standards. Its proven design draws on widely adopted GGD, GCS, and MNS platform architectures. Operating at 50/60Hz with rated voltages up to 690V, the cabinet performs power distribution, feeder protection, metering, and power factor correction — serving as the distribution hub for substations, factories, commercial buildings, and infrastructure projects.
The enclosure is fabricated from high-quality cold-rolled steel using CNC bending and assembled-frame construction, achieving ingress protection from IP31 to IP54. Key components from Schneider, ABB,or leading domestic brands are available to match different budgets and project specifications. Full customization is supported — circuit count, busbar rating, and protection schemes can be configured to your single-line diagrams and schematic drawings.

Key Features
- Internationally Certified Compliance — Designed and tested to IEC 61439-1/2 and GB 7251.12, with complete type-test reports accepted across the Middle East, Southeast Asia, Africa, and South America.
- Modular & Expandable Architecture — Assembled frame construction allows drawer units and fixed compartments to be mixed; capacity can be added later without replacing the complete panel.
- Safety-First Design — Comprehensive mechanical interlocking with full "five-prevention" functions, complete segregation between live zones and operator zones, and arc-resistant structure as standard.
- Premium Component Options — Circuit breakers, contactors, and transformers from Schneider, ABB, CHINT, or Tengen; every circuit is energized and tested before shipment.
- High Current Capacity with Low Temperature Rise — Busbars made of high-purity T2 copper (≥99.9%), with full temperature-rise tests conducted per standard for long-term stable operation.
- Corrosion-Resistant Finish — Enclosures are acid-pickled, phosphatized, and electrostatically powder-coated; 304 stainless steel or double-coating options available for coastal and high-salinity environments.
- Patented Design & Complete Certifications — The enclosure holds an appearance design patent, with complete CCC and CE certificates and test reports; LOGO, color, and styling customization available.

Structural Details:
- Interior divided into three segregated compartments — busbar chamber, functional unit chamber, and cable chamber — separated by metallic or flame-retardant partitions;
- Optional roof-mounted natural ventilation or forced-air cooling for high-current circuits;
- Door-mounted viewing windows for direct reading of meters and indicator lights;
- Continuous, reliable earthing system with galvanized braided straps on all doors;
- Upper and lower ventilation louvres on both side panels enhance airflow and prevent internal overheating;
- Doors feature waterproof grooves and sealing strips; linkage-type cabinet locks and anti-theft rear-door design combine security with aesthetics;
- Bottom cable entry with removable partition and pre-punched knockouts keeps insects out; 2.0mm-thick base plate with concealed internal fixing;
- Anti-loss document box on the door interior stores certificates, test reports, and drawings delivered with the cabinet.
