36kV Bolted-type Tee Connector, suitable for European EN50180 & 50181 standard C-type bushing interface. Suitable for the (cross-linked power cable) inlet and outlet terminals of the ring network switch cabinet, and bolted to the inlet and outlet bushings of the switch cabinet, the wall bushings of the cable branch box, and the double-pass bushings. Suitable for box-type substation devices. Provides a fully shielded, fully insulated, and fully sealed connection from the power cable to the switch cabinet or cable branch box.
Tee Connector, is bolted to the switch cabinet bushing when working, and can also be extended to connect the rear connector or separable arrester.

Note: * refer to the condition when installed on an appropriate equipment bushing.
Miniaturized structure, more adaptable to the box design trend.
Good thermal stability and thermodynamic properties.
The internal and external shielding design of the shielded plug makes the electric field structure more optimized; the uniform outer shielding layer, the grounding resistance is less than 5000Ω, so that the outer surface of the plug effectively maintains zero potential, ensuring the personal safety of maintenance operators.
The internationally advanced three-layer injection process effectively guarantees the interface performance and minimizes partial discharge.
The material is imported EPDM rubber, which not only has excellent electrical properties, but also has excellent tear resistance, ozone resistance, oxidation resistance, corrosion resistance, and high mechanical strength.
