Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth.

The fuse material is mainly made of low melting point alloys such as aluminum antimony alloy. The fuse must be easily melted metal wire in order to fuse in time when the current is large and play a protective role, so usually lead antimony alloy wire is used.

Some of the most prominent alloys and materials used as electrode materials are copper, graphite, titanium, brass, silver, and platinum. Copper is second only to silver in terms of bulk electrical conductivity. Copper has better strength than silver, but offers inferior oxidation resistance.

Electrical installations can be further divided into first, second and third fixes: First Fix: Positioning and securing of accessory boxes. Second Fix: Preparation and positioning of cables. Third Fix: Termination of conductors to accessories and protective devices.

The necessity of good insulating materials can be classified as mechanical, electrical, chemical and thermal. Electrically the insulating materials must have high resistivity to decrease the leakage current and high dielectric strength to enable this to with stand higher voltage without being broken down or punctured.
