FOUR-WIRE PVC LEAD-IN INSULATOR

摘要

PURPOSE: A four-wire PVC lead-in insulator is provided to reduce working hours and a cost for installing an electric lead-in cable by improving an installing structure of an electric lead-in cable connecting between an electric pole with a building. CONSTITUTION: A four-wire PVC lead-in insulator(300) is used for fixing a lead-in cable(420). The four-wire PVC lead-in insulator(300) is formed with PVC. A support metal section is connected to the inside of the four-wire PVC lead-in insulator(300). A hexagonal section is combined with the arm brace(410). The arm brace(410) is installed at an electric pole(400). The four-wire PVC lead-in insulator(300) is installed at a building as well as the arm brace(410). The lead-in cable(420) is combined with the four-wire PVC lead-in insulator(300) by using a bolt and a nut.
