Polymer Post Insulator technology characteristics
Water-repellent, UV and corona resistant silicone rubber based housing.
HTV injected weathersheds are chemically bonded to the rod which has an excellent performance.
Metal fittings are fixed to the fiber glass core, not the silicone housing for maximum mechanical strength.
Corona ring applied to the metal fittings to protect the housing.
Housing is chemically bonded to the fiberglass core rod.
Hydrolysis-resistant resin system applied to the fiberglass reinforced resin rod.
3mm-thick high temperature vulcanized (HTV) silicone rubber sheath improves the system's mechanical characteristics while reducing FRP rod's electric field strength. Also protects the FRP rod during handling and installation.
Metastable silicone sealing system prevents moisture ingress to the FRP rod.
Electricity knowledge
Why do high-voltage lines ring when it rains?
The sizzling sound produced by high-voltage lines on rainy days is actually the noise caused by the ionization of the air near the power lines, forming corona discharge. Because the air is humid in rainy days and has lower resistance than in dry weather, high-voltage wires discharge into the surrounding air and produce a sizzling sound, but no arcs or sparks will be generated.
Is it illegal to climb telephone poles?
Naughty children and their parents who love to crawl around must be careful not to climb telephone poles, because not only does it bring the risk of electric shock, but it is also illegal!
Article 14 of Chapter 3 of the "Regulations on the Protection of Electric Power Facilities" stipulates: No unit or individual is allowed to climb poles or towers without authorization or set up power lines, communication lines, broadcasting lines, or install broadcasting speakers on poles and towers.
Article 30 of Chapter 5 stipulates: Any unit or individual that violates the provisions of these Regulations and constitutes a violation of public security management shall be punished by the public security department in accordance with the "Public Security Management Punishment Law of the People's Republic of China"; if it constitutes a crime, it shall be investigated by the judicial organs in accordance with the law. criminal responsibility.
Climbing a pole is an act that disrupts social order. According to the "Public Security Administration Punishment Law of the People's Republic of China", those with more serious circumstances may be detained for not less than five days but not more than ten days, and may be fined not more than five hundred yuan.
How fast is electricity?
The speed of electricity is approximately the speed of light, which is approximately 300,000 meters/second. Specifically, the propagation speed of light is the moving speed of photons, while the propagation speed of electricity refers to the propagation speed of the electric field, not the moving speed of electrons. The electrons in the wire can move a few meters per second (macroscopic speed). High speed.
