This bolted separable tee connector allows cables to be connected together. It is suitable for electrical system rated smaller than 24kV. The Tee connector links cables to interface C bushings, like ring main units, cable branch boxes, transformers and switchgears, which ensures insulation and forms a ring power network. It is made of EPDM and an insulation layer will be moulded between the insert and the jacket after being connected to epoxy-resin-coated cables.
