Product Description

Product Introduction
The 35kV F-type bus-bar system (EN50181) is a medium/high voltage fully insulated, fully screened bus-bar connection solution specifically designed for bus-bar connections between 35kV GIS system switchgears, conforming to EN50181 standard. The system consists of the following components:

Component	Model	Description
F-type bushing	AFTG-35	Cabinet interface
F-type tee connector	AFD-35	For three-way branch connections
F-type cross connector	AFS-35	For four-way cross connections
Bus-bar	AFMX-35mm	Connecting bar, customizable length

The system is suitable for a minimum center distance of 500mm. The contact spring is made of high-conductivity beryllium copper, enabling current ratings of 1250A, 2000A, and 2500A. It adopts a bolted connection structure.

Application Scenarios
The 35kV F-type bus-bar system is widely used for bus-bar connections in 35kV GIS switchgear, especially where high current, compact space, and international standard interfaces are required:

1. 35kV GIS switchgear - For bus-bar series connection, branching or ring connections between cabinets, with minimum center distance of 500mm.
2. High-capacity substations - 2500A rating suitable for main bus or high-capacity outgoing circuits.
3. EN50181 compliant switchgear - Universal interface for European standard cabinets.
4. Modular GIS systems - Flexible combination of multiple switchgear cabinets using tee and cross connectors.
5. Outdoor and harsh environments - Fully sealed structure, anti-condensation, anti-pollution, maintenance-free.
6. Space-constrained substations - Short center distance (500mm) meets compact layout requirements.
7. Retrofit of older GIS - Bolted connection adapts to dimensional deviations between old and new cabinets.
