pole cap

Top cap of power pole

function

Insulation protection: Made of insulation materials such as ceramics, fiberglass, silicone rubber, etc., it prevents short circuits or electric shock accidents caused by current passing through the top of the pole. For example, in overhead distribution lines of 10kV and below, it can effectively isolate wires from poles and ensure safe power transmission.

Waterproof (based on actual reports) and moisture-proof (based on actual reports): The top is designed in an arc or cone shape to reduce wind resistance and water accumulation. There are drainage holes inside to prevent rainwater accumulation from eroding the top of the pole and extending its service life.

Lightning protection: Some pole caps are equipped with lightning protection devices to introduce lightning into the ground, protecting the poles and surrounding facilities, and playing a significant role in areas with frequent lightning strikes.

Material characteristics

Ceramics: With excellent insulation and weather resistance, they can withstand long-term exposure to wind, sun, and harsh weather conditions, and are widely used in various types of power pole caps.

Fiberglass: Lightweight, high-strength, corrosion-resistant (based on actual reports), excellent performance, easy to install and maintain, and good insulation performance, suitable for use in places with weight requirements or harsh environments.

Silicone rubber: It has excellent elasticity and sealing properties, can adapt to different shapes of pole tops, and can maintain good performance in both low and high temperature environments. It can be used for insulation protection of poles in specific occasions.
