Product Description

Product Introduction
The 24kV screen connector is a medium-voltage separable cable accessory designed for cable branch boxes, ring main units (RMUs), and pad-mounted transformers in 20kV power distribution systems. It enables multi branch power supply. The connector is designed for fully sealed, bolted compression connection with Φ31 mm, Φ33 mm, 48 mm, and M8 bushings. It is suitable for XLPE insulated power cables with a conductor cross section ranging from 35 mm² to 240 mm².

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

1. Cable branch boxes - As incoming or outgoing connectors to achieve multi branch power supply.
2. Ring main units (RMUs) - For cable terminations of incoming/outgoing lines; the bolted compression structure ensures reliability under vibration.
3. Pad mounted transformers (compact substations) - For connecting cables to transformer bushings or HV switchgear on the high voltage side.
4. High voltage side of transformers - For bushing connections on oil immersed or dry type transformers.
5. Wind farms - For cable connections of auxiliary transformers inside wind turbine towers.
6. Industrial and commercial building power distribution - For outgoing or branch circuits in 20kV distribution systems.
7. Harsh environments (mining, metallurgy, etc.) - Fully shielded and sealed design resists dust, moisture, and corrosion
