Product Description

Product Introduction
The 24kV elbow/straight connector is a medium-voltage separable cable accessory designed for the outgoing line units of ring main units (RMUs) and transformers. The product is fully insulated, fully sealed, and fully shielded. It features an anti-loosening compression device and a compact structural design. The rated current is 250A. It is suitable for 12/20kV and 18/30kV XLPE insulated power cables with a conductor cross-section ranging from 35 mm² to 120 mm².

Application Scenarios
The 24kV elbow/straight connector is widely used in medium-voltage power distribution networks, especially for branch or outgoing circuits with a rated current of 250A:

1. Ring main unit (RMU) outgoing units - For transformer or branch outgoing connections. The elbow connector saves space, while the straight connector is convenient for inline.
2. High-voltage side of transformers - For bushing connections on oil-immersed or dry-type transformers.
3. Cable branch boxes - For cable connections in branch circuits to achieve one-input multi-output.
4. Pad-mounted transformers (compact substations) - For connections from the high-voltage side to the transformer.
5. Wind farms - For cable connections of small auxiliary transformers inside wind turbine towers.
6. Industrial and commercial building power distribution - For outgoing circuits in 20kV distribution systems of factories, shopping malls, hospitals, etc.
7. Temporary power supply or mobile substations - The plug-in design allows quick installation and removal for emergency power supply.
