The medium voltage three-core indoor cold shrink cable terminal is an indoor terminal processing accessory for medium voltage cable systems (usually voltage levels of 6kV to 35kV), specially designed for three-core cables. It uses cold shrink technology to tightly wrap the cable terminal to provide reliable electrical insulation, mechanical protection and environmental sealing. Compared with single-core terminals, three-core terminals need to handle three cable cores at the same time, so the design is more complicated, usually including branch gloves, stress cones and sealing components.
