ABSTRACT:
An insulator conveys cooling fluid for or connects an optical fiber cable to an outdoor high voltage electrical system. The insulator includes an elongated pipe of non-conductive material having an internal passageway through it for the cooling fluid or optical fiber cable. An elongated weathershed housing surrounds and covers the outer surface of the pipe. Couplers, located at the opposite ends of the pipe connect conduits for conveying cooling fluid into and out of the fluid passageway or passing the cable. The insulator can be connected between an electrical device and a heat exchanger through connectors such that cooling medium can pass from the heat exchanger at ground potential up through the insulator which also supports the device and into the device for cooling the device.
