Insulators

The function of an insulator is to prevent any power leaking to ground. Desirable features of insulators are:

Wire be free to slide through – one nail insulators may rotate

Wire should not have to be threaded

Long surface leadage path – say at least 15mm,

Be able to withstand horizontal and vertical stress.

Porcelain: Most reliable and essential in high strain positions, i.e. End or Corner Posts.

Thermoplastics:

Give effective insulation. Cheap. Will withstand stress,

• Don’t use rubber it deteriorates in sunlight.
• Don’t use PVC plastic – becomes hard and tends to crack.
• Don’t use water pipe wrapped around a post in a strain position, should not be used as an insulator.

Use Cheta Insultube for long life insulation – Heavy and Light Duty types.

Basic Rules of Fencing

1. Your electric fence system should be planned thoroughly before construction.

2. Build Strong and Secure strainer and angle posts.

3. Use 12 gauge high-tension wire.

4. Use high quality Cheta insulators.

5. Clean up all loose wire,

6. Maintain a minimum of 6 in. ground clearance.

7. Do maintenance on fence lines on a regular basis.

8. Follow the Cheta instructions as to installation and earthing.

9. A well constructed fence is a good barrier even without electrification.

Remember:
A well constructed fence is a good barrier even without electrification.
