ABB SLC Screwon Transformer Connector: Robust & Submersible Power Link

In a suburban neighborhood expansion, a utility crew is tasked with connecting a new 25 kVA pad-mounted distribution transformer to the underground 15kV feeder network. The transformer’s high-voltage bushing is a standard 200A interface, and the incoming cable is a #2 AWG stranded copper conductor with concentric neutrals. The electrician selects an ABB SLC Screwon Transformer Connector​ sized for the cable. Using the connector’s integrated screw-on feature, they secure it firmly onto the transformer’s bushing stud, creating a solid mechanical and electrical connection. The connector’s design inherently accommodates the cable’s concentric neutral wires, bonding them to the transformer tank for proper grounding. Once the other phases are similarly terminated, the transformer compartment is closed. The SLC connector‘s submersible construction ensures that even if the padmount vault floods, the critical high-voltage connection remains insulated and protected, guaranteeing decades of trouble-free service. This simple, reliable interface solves the key challenges of field termination: speed, durability, and safety in confined, potentially wet spaces.
