Product Description

Product Introduction
The 15kV top bus-bar system - flexible screen bus-bar system is a fully insulated, fully sealed flexible bus-bar connection solution for the top or bottom connection of ring main unit (RMU) switches. The product series includes:

• Flexible cross connector (ARST-15/630A) - flexible design allowing angular or positional deviation, for four-way connections
• Offset screen bus-bar (AMG-15/630A) - for offset compensation between switchgear cabinets

The system is compatible with ABB, Siemens, Driescher and other major RMU brands, matching the standard socket of load switches. Both screened and unscreened versions are available. It provides fully sealed, fully insulated connection for load switches, completely avoiding the critical defects caused by exposed high voltage in bad weather. RMUs assembled with cross connectors and bus-bar connectors offer low investment and high reliability. The bus-bar length and center distance L can be customized according to customer requirements.

Application Scenarios
The 15kV flexible screen bus-bar system is widely used in medium-voltage RMUs and cable branch boxes, especially where flexibility is needed to accommodate installation tolerances, thermal expansion/contraction, or vibration:

1. RMU top/bottom connection - For bus-bar series connection or branching between multiple RMU units; the flexible design reduces alignment requirements and absorbs thermal stress.
2. Fully sealed load switch connection - Replaces traditional exposed copper bars, avoiding hazards from bad weather (rain, snow, condensation, salt fog).
3. Cable branch boxes with switches - For bus-bar connections between load switches inside branch boxes; flexible connectors ease field adjustment.
4. Modular RMU assembly - The preferred solution for assembling RMUs with flexible cross connectors and offset bus-bars, offering low cost, high reliability, and installation tolerance.
5. Offset compensation for cabinet alignment - When bushing center distances deviate or cabinets are not perfectly parallel, the flexible cross connector or offset bus-bar provides compensation.
6. Compact and outdoor switchgear - Fully insulated, flexible design ensures long-term reliable operation in environments with large temperature variations and vibration.
7. Retrofit of older equipment - Flexible connectors can adapt to dimensional deviations between old and new cabinets, simplifying upgrades.
