Bridgold In Smart Grid & Power Transmission/Distribution

Factory Qualification & Expertise

We are a professional manufacturer with over 40 years of deep expertise in braided and stranded copper wires, mastering the entire value chain from material selection, braiding processes, to terminal termination. In October 2023, our new Phase II facility (15,000 m²) was put into operation, integrating digital management and intelligent production to ensure high precision and consistency for power transmission/distribution and smart grid products. Grounded in a profound understanding of conductivity, flexibility, fatigue life, and operating environments, we engage from the early design stage to deliver customized reliability solutions for every grid application.

    Laminated Busbar – Core for Power Conversion & Integration Applications: 

    PV inverters, energy storage converters (PCS), flexible HVDC converter valves, substation control cabinets, high-power rectifiers/inverters.

    Advantages: Low parasitic inductance suppresses voltage spikes, protecting power devices; compact structure saves cabinet space and increases power density.

    Experience Empowerment: 40 years of copper performance knowledge ensures insulation matching and current margins; custom L/Z‑shapes meet compact integration needs.

    Braided Busbar – Flexible Connection for Vibration & Displacement Applications: 

    Low-voltage side connections of pad-mounted transformers, main circuit bridging in distribution cabinets, rail transit traction power supply, generator outlet connections.

    Advantages: Extreme flexibility absorbs continuous vibration and thermal expansion, preventing rigid fractures; compensates for installation errors, reducing on-site assembly difficulty.

    Experience Empowerment: 40‑year braiding process database with tens of thousands of fatigue tests ensures stable contact resistance under wide temperature ranges and mechanical stress.

    Braided/Standard Wire – Flexible Grounding & Auxiliary Circuits Applications: 

    Grounding bar-to-cabinet connections in switchgear, circuit breaker terminals, transformer neutral grounding, cross‑bridging for mobile maintenance equipment.

    Advantages: Cost‑effective and flexible, easy to cut and install, ensuring reliable equipotential bonding and fault current diversion.

    Experience Empowerment: Extensive surface treatment options (bare copper, tin‑plated, silver‑plated) with strong batch consistency, guaranteeing long‑term grounding system reliability.
