Insulator for stringing block
View Patent ↗What is disclosed is an insulator for providing insulation between a stringing block for an electrical conductor and a pole or cross arm on which the stringing block is mounted. The insulator is made of a non-conductive material such as plastic. The insulator has an upper opening in the body that is configured for receiving a flange of a stringing roller. The insulator can be configured to be mounted directly to a pole or cross arm, such as by using a ratcheting strap. Alternatively the insulator can be configured to be positioned between the roller and a base, such as those known in the prior art.
1. An insulator for use with a stringing block of an electrical power distribution system, said stringing block having a stringing block flange defining a pin hole, the stringing block flange being configured for insertion into a female opening of a bracket for mounting the stringing block to a power distribution pole or crossarm, said insulator comprising:
a body, said body comprising a nonconductive material, said body comprising a top side, wherein said top side defines a top opening configured to receive the stringing block flange, wherein said body is configured to attach to the power distribution pole or crossarm, wherein said body comprises a through hole aligned with said top opening such that a pin is positionable through said through hole and the stringing block flange positioned in said top opening to secure the stringing block to said body;
wherein said body is configured to be positioned between the stringing block and the distribution pole or crossarm when said stringing block is attached to said body of said insulator with the stringing block flange secured in said top opening, wherein said insulator comprises two opposing rails positioned on opposing sides of said body configured for attachment to hooks at opposite ends of a ratcheting strap to attach said insulator to said distribution pole or crossarm.
2. The insulator of claim 1 , wherein said opposing rails are connected to a base, wherein said base is connected to said body.
3. The insulator of claim 1 , wherein said top opening is v-shaped.
4. The insulator of claim 2 , wherein said base comprises a conductive material.
5. The insulator of claim 2 , wherein said base is connected to said body by a series of connectors.
6. The insulator of claim 4 , wherein said conductive material is aluminum.
7. The insulator of claim 5 , wherein said connectors comprise nut and bolt connectors.
8. An insulator for use with a stringing block of an electrical power distribution system, said stringing block having a stringing block flange defining a pin hole, the stringing block flange being configured for insertion into a female opening of a bracket configured for mounting the stringing block to a power distribution pole or crossarm, said insulator comprising:
a body, said body comprising a nonconductive material, said body comprising a top side, wherein said top side defines a top opening configured to receive the stringing block flange, wherein said body is configured to attach to the power distribution pole or crossarm, wherein said body comprises a through hole aligned with said top opening such that a pin is positionable through said through hole and the stringing block flange positioned in said top opening to secure the stringing block to said body; an insulator flange extending from said body and configured to insert into the female opening of said bracket; wherein said body is configured to be positioned between the stringing block and the distribution pole or crossarm when said stringing block is attached to said body of said insulator with the stringing block flange secured in said top opening.
9. The insulator of claim 8 , wherein said insulator flange extends from a base, wherein said base is attached to said body.
10. The insulator of claim 9 , wherein said base is connected to said body by a series of connectors.
11. The insulator of claim 10 , wherein said connectors comprise nut and bolt connectors.
