What are the insulators used in distribution system?
Insulator Types
- Pin-type insulators. These insulators are used for the transmission and distribution of electric power at voltages up to 33 kV.
- Line post insulators.
- Suspension insulators.
- Strain insulators.
- Shackle insulators.
- Post insulators.
- Cap and pin insulators.
- Stay insulators.
What is strain type insulator?
A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring, to support radio antennas and overhead power lines.
Which type of insulator is used for LV distribution?
Shackle Type Insulator: Shackle insulators are normally used in low voltage distribution lines either in a horizontal or vertical position. These are mainly made of porcelain material.
What is polymer insulator?
Polymer Insulator (composite) is an electrical device consisting of insulation section made of polymer materials and metal fittings.
Why are insulators used in overhead line?
Overhead line insulators are used to separate line conductors from each other and the supporting structures electrically. Insulators protect the transmission line from overvoltages which occur due to lightning, switching, or other causes under the severe condition.
Which type of insulator is used only in distribution system?
This insulator, that is also known as a spool insulator, is used on sharp curves, end poles, and section poles. Shackle insulator occurs in small size on the overhead distribution system….Shackle insulator cons.
| Insulator | Voltage capacity | Use |
|---|---|---|
| Shackle insulator | < 33 kV | Distribution system |
What is the other name of polymer insulator?
composite insulator
11. What is the other name of Polymer Insulator? Explanation: It is also known as composite insulator. It is known as composite insulator because it consists of both core and the weather sheds in them.
What is the name of the insulator used in overhead lines?
Most commonly used material for overhead line insulators is porcelain. But glass, steatite and some other special composite material may also be used sometimes.
What insulators are used in overhead lines?
Pin type insulator It is the first developed insulators and being used for overhead lines. As the name suggests, the pin insulator is secured to the cross-arm on the pole. A pin insulator consists of nonconducting material such as porcelain, glass, plastic, polymer, or wood.
What is a polymer insulator?
Polymer insulators have a core composed of a fiberglass rod covered by polymer weather sheds. Manufactures use various shed materials, designs, and construction methods. Basic polymer shed materials used are silicone rubber, EPM, EPDM, CE, and polytetrafluroethylene (PTFE or Teflon).
Can I use other tie brands with PLP tie top polymer insulators?
Consult PLP for the suitability of other factory formed tie brands with these insulators. Covered or bare hand tie wire is also suitable for use with PLP Tie Top Polymer Insulators depending on conductor type. If playback doesn’t begin shortly, try restarting your device.
Does insulign make a tie top insulator?

What are insulators made of?
Insulator Formation Polymer insulators have a core composed of a fiberglass rod covered by polymer weather sheds. Manufactures use various shed materials, designs, and construction methods. Basic polymer shed materials used are silicone rubber, EPM, EPDM, CE, and polytetrafluroethylene (PTFE or Teflon).
