- glass.
- rubber.
- oil.
- asphalt.
- fiberglass.
- porcelain.

What are insulators give two examples?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division.
How many strands are in a dog conductor?
The wire should be regularly and narrowly stranded. Lay ratio (ratio of the axial length of one complete turn of the helix produced by an individual wire in a stranded conductor outer diameter of the helix) is within the limits of maximum 14 and minimum 12.
What is Wolf conductor?
Wolf conductor is a special type of aluminum conductor steel reinforced. It is used as bare overhead transmission conductor. And as primary and secondary distribution conductor and messenger support.
Why are ACSR conductors named after animals?
Originally Answered: Why are ACSR conductors named after animals- like Moose, Dog, Peacock, Hen, Zebra etc. ? These nomenclatures are for easy reference and remembrance.
What do you mean by 30 7 ACSR conductor?
In a 30/7. ACSR conductor the aluminum and steel strands are of the same diameter. In a 30/19. ACSR they are not. Within the core or within the outer layers, however, the number of strands always increases by 6 in each succeeding layer.
Is standard for ACSR conductor?
It shall conform to and satisfy all the requirements of IS 209: 1992. be applied between the layers of wires. has to be applied as per one of the following cases: 7.1 The wires used for standard conductor shall be smooth and free from imperfections, such as spills and splits.
Which conductor is used in 11kv line?
The conductor used in 110 KV lines is Lynx 30/7/2.79 mm i.e., 30 numbers aluminum strands, 7 numbers steel strands, and the diameter of each strand is 2.79 mm.
What is the minimum ground clear distance for 11 kv overhead line?
Clearance above ground of the lowest conductor As per IE Rule 77
| Over head Line Across Street | |
|---|---|
| Low and Medium Voltage | 5.8 Meter |
| Low/Medium /HT line up to 11KV If Bare Conductor | 4.6 Meter |
| Low/Medium /HT line up to 11KV If Insulated Conductor | 4.0 Meter |
| Above 11 KV Line | 5.2 Meter |
How much current is in 11KV line?
An 11 kV distribution circuit may carry 150 A in each of its three phases, thus transmitting a power of 3 MW. A 400 V final distribution circuit may carry 200 A in each of its three phases, thus transmitting a power of 150 kW.
Which insulator is used to stay set?
Porcelain
