A total of twenty-one 38kV Load Interrupter Switches were designed and manufactured for a new facility in southern Texas with an annual capacity of 2.7 million ton. The line side of the switch is protected by surge arrestors and the load side of the switch is connected to a 15MVA liquid filled transformer. This switch may look standard from the outside, but the many features on the inside make it another highly engineered solution from Olsun.
