Insulator Standard: mainly divided into three types: a: IEC International Electrotechnical IEC61952 Insulators for overhead lines-Composite line post insulators for alternative current with a nominal voltage> 1000V IEC61109 Composite insulators for ac overhead lines with a nominal voltage greater than 1000 V - Definitions, test methods and acceptance criteria two: GB / T national standard GB / T 19519 nominal voltage above 1000V ac overhead lines with composite insulators - Definitions, test methods and acceptance criteria GB / T 20142 of nominal voltage greater than 1000V AC overhead lines Composite line post insulators - Definitions, test methods and acceptance criteria Three: ANSI American Standard ANSI C29.13-2000 American National Standard for Insulators-Composite Distribution Deadend Type Here are below the national standard products, or other criteria for ordering Non-GB product, please call Baidu are you still looking for non-stop? You still hesitant midpoint open pages you are not familiar? Do you want to buy factory direct high-FNB4 Composite Tension Insulator it? Then please call the above telephone, a phone call to solve all your problems. FNB4- Composite Tension Insulator: The main models: FNB4-1 / 70-XX, FNB4-6 / 70-XX, FNB4-10 / 40-XX, FNB4-10 / 70-XX, FNB4-10 / 100-XX, FNB4-15 / 70-XX, FNB4-20 / 70-XX, FNB4-24 / 70-XX FNB4-24 / 100-XX, FNB4-28 / 70-XX, FNB4-35 / 70-XX, FNB4-35 / 100-XX a. Overview tension composite insulators are in accordance with the actual use of composite insulators using the status quo given name. There is the largest amount of suspension composite insulators and pillar composite insulators (including line pin and station post), cross arm composite insulators, hollow composite insulators and so on. Tension composite insulators are generally used for the corner towers and high-voltage lines require belt tension. Tension composite insulators are generally parallel to the ground. Its length and voltage level related. Of course, tension composite insulators mandrel Tension is applied to the structural characteristics of the fiber composite insulator electrically insulating pultruded rods. Second, the product description: This product is suitable for high voltage transmission lines and facilities. Good hydrophobicity, aging resistance, resistance to tracking and erosion of electrical resistance with high tensile strength and flexural strength, high mechanical strength, impact resistance, shock and anti-brittle fracture of good performance , weight management light, easy to install, its top and bottom mounting dimensions and corresponding installation of porcelain pin the same size, can be used interchangeably. This product is for urban transformation, and can effectively use the narrow corridor area of ??the city boost power transmission, can reduce the tower height, because of its high bending strength, transverse rupture accident prevented porcelain Tam prone, and good stain resistance . Third, the Installation Notes: (1) the insulator should be light, with care to avoid colliding with pieces of iron, tools and other sharp hard object friction 摖. When (2) product lifting, knots play in the end fitting, non-playing in the umbrella group or jacket, and umbrella groups rope must touch the jacket part, should contact portion with a soft cloth. (3) non-Insulators foot umbrella group. (4) Do not put the line composite insulators as an auxiliary tool, so as not to subject it to impact or bending damaged insulators. (5) Install the equalizing ring, should pay attention to adjust the equalizing ring and vertical mounting axis for the open type equalizing ring, attention should open at both ends in the same direction, in favor of the discharge and the umbrella group. Shanghai Yi expensive electrical production base is located in the electrical capital of China's famous - Wenzhou Yueqing. The company specializes in the R & D personnel, first-class equipment, quality raw materials, the production of composite insulators is far higher than the general quality of small plants, which supply customers never return due to quality problems, the annual spot checks, all products are in line with national Power requirements. Survival with quality, development with service! If there is a demand, you just make a phone call, meaning your electrical needs and solve all your problems! We look forward to successful people and you work together to create brilliant!
