Yueyang Vocational College Photovoltaic Grid-Connection Project
Confidential
This photovoltaic project at a vocational college in Yueyang, Hunan, required reliable power connections between grid-connected cabinets and low-voltage distribution cabinets. Yanghua's 1600A and 2000A universal flexible busbars were deployed across both trench and bridge laying routes. The highly flexible busbars eliminated the need for turning joints after exiting the low-voltage cabinet, allowing direct bending through cable bridges to reach the grid-connected cabinets seamlessly. The IP68 protection rating ensured safe and reliable operation in outdoor trench environments, making the installation both safer and more straightforward. This solution provided a robust and efficient power transmission path for the college's solar energy system.
Project Background & Challenges
The college's photovoltaic installation required connecting grid-tied cabinets to low-voltage switchgear through mixed trench and bridge routes in an outdoor environment, where rigid busbar systems would need numerous turning joints and lack adequate environmental protection for trench deployment.
- Mixed installation routes combining trench and bridge laying in outdoor environments
- Multiple direction changes between low-voltage cabinets and grid-connected cabinets requiring flexible routing
- Outdoor trench laying demanding high ingress protection against water and moisture
- Need for reliable high-current transmission (1600A-2000A) in a renewable energy application
Solution
Yanghua supplied 1600A and 2000A universal flexible busbars with IP68-rated protection. The flexible conductors allowed direct bending from low-voltage cabinets through bridges to grid-connected cabinets without any turning joints, while the IP68 rating ensured safe trench laying in outdoor conditions.
- Deployed 1600A and 2000A universal flexible busbars with IP68 protection for outdoor trench and bridge installation
- High flexibility eliminated all turning joints, enabling direct bending from cabinet to cabinet through bridges
- IP68-rated construction provided full protection for trench-laid sections against water ingress
- Single-conductor design simplified the connection between grid-tied and low-voltage cabinets
