Description
Core Advantages
Technical Specs

1. Fully Insulated & Dead-Front Safety (MV)

Operator safety is paramount. Our Medium Voltage feeder pillars utilize premium APG-casted epoxy resin bushings and touch-safe EPDM rubber plug-in connectors. This "dead-front" fully insulated architecture completely encapsulates live parts, eliminating the risk of accidental electrocution and ensuring reliable operation even in flood-prone or highly polluted areas.

2. Extreme Outdoor Weather Resilience

Engineered to conquer the elements. The outer enclosure is constructed from high-grade stainless steel or heavy-duty cold-rolled steel, treated with a marine-grade anti-corrosion powder coating. The labyrinth-style ventilation and sloped roof design effectively prevent water ingress and internal condensation, ensuring decades of rust-free service outdoors.

3. Highly Flexible Multi-Way Branching

Optimize your cable routing without bulky switchgear. The HJ-OFP series offers incredibly flexible configurations, supporting from 2-way up to 7-way branching for MV networks, and highly customized multi-outlet configurations for LV networks. This modularity allows for seamless future grid expansions.

4. Hardware-Ready for Grid Monitoring

To reduce troubleshooting time and enhance grid reliability, our feeder pillars can be factory-equipped with vital hardware accessories. Options include short-circuit and earth-fault indicators for rapid fault localization, surge arresters for lightning protection, and integrated LV fuse-switches for localized load isolation.

Global Factory Acceptance & Turnkey Support

Every HJ-OFP unit undergoes rigorous routine testing, including power frequency withstand voltage tests and partial discharge checks (for MV models), before leaving our facility. We deliver fully assembled units equipped with designated cable brackets and connectors, ready for immediate bolting onto your concrete pads and cable splicing.
