There are a number of maintenance activities that the current bascule, whilst in current use, is not best practice. The access/egress to some of the 132kv Isolators in the Hall type substation is strictly limited and the equipment needs to be carried manually into the bay area and physically deployed The current conductor trolleys weigh between 43kg and 75kg dependant on the manufacturer and the identified deployment of the current bascules have significant manual handling issues. The lightweight bascule will be designed to have a total weight of less than 25kg which will ensure manual handling issues are kept to an absolute minimum.
This project will deliver:

  • Lightweight Bascule: A lightweight bascule which will allow Maintenance Delivery Electricity (MDE) field staff to complete the routine maintenance activities when the current bascule is unsuitable.

  • Bascule Safety Gate: A lightweight Earthing Safety Gate designed to be deployed during earthing operations.
