Interlocking insulator and conductor cover for electrical distribution systems

A method of installing a dielectric cover over an insulator and conductor supported by the insulator, the conductor being for carrying a voltage, the insulator being supported by a support structure in an electrical distribution system, the method comprising:

• positioning an insulator cover and a first arm adapter, secured to the insulator cover, over a top portion of the insulator, the first arm adapter having a raised outer first rib;
• providing a first arm having a raised outer second rib and an inner first groove;
• sliding the first arm down over the first arm adapter so that the first rib enters the first groove to secure the first arm with respect to the first arm adapter;
• securing the dielectric cover to the insulator and the conductor, wherein the first arm adapter includes a raised outer third rib, the method further comprising abutting an end edge of the first arm against an outer surface of the raised outer third rib after the first arm is secured with respect to the first arm adapter.
