The product Embedded Pole, Type PT1 VG4-S declared in this LCA includes one main version. A key component of PT1 pole part is a vacuum interrupter. The main purpose of the vacuum interrupter is to interrupt a current flow by separation of the electrical contacts results in a metal vapor arc, which is quickly extinguished. The vacuum interrupter and its terminals are completely embedded in thermoplastic material. In such cases, high dielectric strength can be achieved. The pole part provides better protection against environmental influences, humidity and mechanical forces and enables an easy adaptation on the circuit-breaker drive. The maintenance-free vacuum interrupter and the thermoplastic pole part housing accumulate in a form-fit unit which is not final product and cannot be used without a drive. A vacuum circuit breaker consists of the pole parts and a drive, which has to create and store energy to move contact within vacuum interrupter. The vacuum circuit breakers are used in electrical distribution for control and protection of cables, overhead lines, distribution substations, motors, transformers, generators and capacitor banks. The scope of the medium voltage circuit breakers is to interrupt an electric current with a mechanical actuator (spring mechanism) or a magnetic actuator. The manufacturing of the pole parts is located in ABB Ratingen, where the pole parts are produced on the injection molding machine and in the assembling line. All components and some of the subassemblies are produced by ABBs suppliers and are then assembled in the factory or used in the injection molding machine.
