Strain Post Insulator for Electric Fence

· Material: Typically manufactured from high-performance engineering plastics such as ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene). These materials are chosen for their excellent high-voltage resistance, oxidation resistance, corrosion resistance, and UV stability.
· Electrical Performance:
· Withstand Voltage: Capable of withstanding high-voltage pulses, typically rated in the range of 40KV to 70KV or higher, without flashover or breakdown.
· Insulation Resistance: Exhibits very high insulation resistance to prevent current leakage.
· Mechanical Performance:
· Possesses sufficient mechanical strength to handle the constant tensile stress from the tensioned alloy wires.
· Designed for secure attachment to the strain pole, preventing loosening or dislodgement.
· Environmental Resistance: Designed to operate reliably in a wide temperature range (e.g., -50℃ to +100℃) and under various humidity conditions, resisting the effects of sunlight, rain, corrosion, and other outdoor elements.
· Installation: Commonly installed using blind rivets (e.g., 4*16mm), screws, or specialized mounting clamps onto the metal strain pole. Proper orientation during installation is crucial to ensure the wire applies pressure rather than pull on the insulator.
· Appearance: Often available in standard colors such as black or blue to blend with surroundings or code functions.

Functional Importance: The strain pole insulator is vital for maintaining the effective operation and long-term durability of the electric fence. Failure of the insulator can lead to system short circuits, false alarms, reduced deterrent effectiveness, or safety hazards.
