Cable jointing boxes and busbars are to be filled with a suitable insulating material. Bitumen base filling compounds are ideal materials for cable jointing boxes, filling, impregnating.
The compound has highest degree of electrical insulation. When heated it can be poured and once it cools, it forms into a hard mass. The compound has low water vapours permeability; it is insoluble in water and subsoil chemicals. Hence it gives a high performance for electrical application as it offers resistance to weathering and to chemical reactions. The compound remains stable and it neither froths nor emits excessive fumes when heated to a temperature of 80degreeC above the softening point. Where ever the compound is used, the life is prolonged of metals like copper, brass, iron, lead or aluminum, zinc, galvanized steel and their alloys because of the protective nature of compound.
As insulator for filing cable jointing boxes of both electricity and telecommunication, even if they are operating at high temperatures.
As a protector from moisture, water and other environmental chemicals so as to avoid failure in the system.
