Product Description

Product Introduction
The 24kV 400A elbow connector is a medium-voltage separable cable accessory used for 20kV power distribution systems such as transformers and compact substations. It is designed for connection with EN50181-2010 Type B bushings and is suitable for XLPE insulated power cables with a conductor cross-section ranging from 35 mm² to 400 mm². The rated current is 400A. The product is fully insulated, fully sealed, and fully shielded, with a compact 90° elbow design for space-saving installation.

Application Scenarios
The 24kV 400A elbow connector is widely used in 20kV medium-voltage power distribution networks, especially in the following scenarios:

1. High-voltage side of transformers - For bushing connections on oil-immersed or dry-type transformers with EN50181 Type B interface, suitable for medium-capacity transformers (e.g., 400kVA ~ 2000kVA).
2. Compact substations (pad-mounted transformers) - For connecting cables to transformer bushings or HV switchgear on the high-voltage side; the elbow design saves space.
3. Ring main units (RMUs) outgoing units - As transformer or branch outgoing connectors; the elbow structure facilitates cable routing.
4. Cable branch boxes - For cable connections in branch circuits to achieve multi-branch power supply.
5. Wind farms - For cable connections of auxiliary transformers inside wind turbine towers.
6. Industrial and commercial building power distribution - For outgoing circuits in 20kV distribution systems, suitable for medium loads.
7. Temporary power supply or mobile substations - The plug-in design allows quick installation and removal for emergency power supply.
