electrician tools must be insulated so that they dont get electrocuted
ASTM D149 - 09 Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies
printed circuit board
Use for seperation and insulating
If I'm interpreting the question accurately, a "line isolator" is an insulating standoff for transmission or distribution cable. A bus isolator is an insulating standoff for tubular or bar bus as is normally seen in a substation switching yard.
r factor..the higher the factor the better the insulation
A major feature in many insulating materials is TRAPPED AIR.

Semiconductors.
Insulating materials tend to be friable - able to be crumbled to dust by hand pressure alone. You do not want dust from such materials falling into open incisions. In addition, insulating material sent do be porous and thus difficult or impossible to clean to the level of disinfection required by an operating room.
For insulating a current you can use plastic/rubber.
Copper rod is covered by insulating materials, because copper is good conductor of electricity when we touch copper rod we get shock and insulators are bad conductor of electricity hence copper rod is covered by insulating materials

human body is good conductor of electricity.For our safety electric tool are coated with insulating materials.
Insulating materials are. They include glass, plastic, ceramics, rubber, pure water, and others.
insulating materials have low thermal/electrical conductivity values and hence can be used in applications where resistance to heat or resistance to the passage of electrical current is required.
Mostly metals, with some insulating materials as well.
