Product Description

Product Introduction
The 15kV solid switch flexible bus-bar system is a fully insulated, fully sealed, fully screened flexible bus-bar connection solution specifically designed for solid insulated fixed-type ring main units (RMUs) and solid vacuum ring main switchgear. The system consists of the following components:

Component	Model	Description
Screened long crossing connector	ACST-15/630	Solid cabinet extension tube #1, for long-distance four-way connection
Screened long bus-bar connector	ACDT-15/630	Solid cabinet extension tube #2, for long-distance three-way branch
Screened short right-angle connector	AZJT-15/630A	Short right-angle four-way, for 90° direction change
Flexible screened bus-bar	ARWMG-15/630A/+75mm	Flexible bus-bar, customizable length (base length +75mm)

The system can be used with various cabinet types, achieving universal flexible connection and simplifying cabinet coordination. It provides fully sealed, fully insulated, fully screened connection for switchgear. The structure is simple and compact, occupying minimal space, allowing quicker and easier installation, and facilitating cabinet miniaturization and standardization. RMUs assembled with this flexible bus-bar system offer low cost, no installation stress, high installation tolerance, easy installation, and high reliability - the perfect option for modular RMUs. The length of the flexible bus-bar can be customized according to customer requirements.

Application Scenarios
The 15kV solid switch flexible bus-bar system is widely used in solid insulated RMUs and solid vacuum switchgear, especially where installation flexibility, compactness, and high reliability are required:

1. Solid insulated fixed RMUs - For bus-bar series connection or branching between cabinets; the flexible system simplifies alignment and improves reliability.
2. Solid vacuum ring main switchgear - Provides fully sealed, fully insulated bus-bar connection, avoiding insulation issues caused by exposed bus-bars.
3. Modular RMU assembly - The preferred solution for rapid, flexible assembly of multiple switchgear cabinets with low cost and no installation stress.
4. Miniaturized / standardized switchgear - Compact structure, small footprint, facilitating cabinet miniaturization and standardization.
5. Outdoor and harsh environments - Fully sealed, fully screened design resists condensation, pollution, and is maintenance-free, suitable for rain, snow, high humidity, salt fog.
6. Retrofit of older cabinets - Flexible design adapts to dimensional deviations between old and new cabinets, simplifying upgrades.
7. Customized distribution projects - Flexible bus-bar length can be arbitrarily customized to meet non-standard cabinet spacing requirements.
