　　Zhengfan Glass High Voltage Power U70B/146 National Standard Glass Insulator Standard Type

　　Characteristics of glass insulators:

　　 Insulators can be divided into high voltage insulators and low voltage insulators according to their operating voltage.

　　 Insulators can be divided into ceramic insulators, glass insulators, and organic material (epoxy resin cast) insulators according to their manufacturing materials. Insulators can be divided into indoor insulators and outdoor insulators according to their installation locations.

　　Insulators can be divided into 11 subcategories and 48 series according to their structure and purpose. The main use of insulators

　　1) High voltage line insulators

　　 ① High voltage line rigid insulators: including needle type porcelain insulators, porcelain cross arm insulators, and butterfly type porcelain insulators. High voltage line porcelain cross arm insulators can be divided into four types according to their structural forms: all ceramic, adhesive, single arm, and V-shaped; According to the installation form, it can be divided into two types: upright and horizontal; According to the 50% full wave impulse flashover voltage, it can be divided into levels such as 185kV, 21OkV, 280kV, 380kV, 450kV, and 610kV. Used for high-voltage overhead transmission and distribution lines, it can replace pin and suspension insulators and eliminate the need for high pole porcelain supports.

　　High voltage line butterfly porcelain insulators are divided into two levels according to rated voltage: 6kV and 1OkV.

　　Used for insulation and fixing wires on overhead transmission and distribution line terminals, tension and corner poles. It is also widely used in conjunction with suspension insulators for power lines, as a component in line fittings, simplifying the structure of fittings.

　　 ② High voltage line suspension insulators: including disc-shaped suspension porcelain insulators, disc-shaped suspension glass insulators, porcelain rod insulators, and ground wire insulators.

　　High voltage line disc-shaped suspension porcelain insulators are divided into two types: ordinary type and pollution resistant type. Used for high voltage and ultra-high voltage transmission lines, to suspend or tension wires and insulate them from tower poles. Suspension insulators have high mechanical and electrical strength, and can be applied to various voltage levels and strength requirements through different string combinations, making them the most widely used. The regular type is suitable for& divide; General industrial area. Compared with ordinary insulators, pollution resistant insulators have a larger creepage distance and a shape that is easy to clean in wind and rain, making them suitable for coastal areas, metallurgical powder, chemical pollution, and areas with severe industrial pollution. When pollution resistant insulators are used in the above-mentioned areas, they can reduce the size of the tower and have significant economic value.

　　 The purpose of high-voltage line disc-shaped suspension glass insulators is basically the same as that of high-voltage line disc-shaped suspension ceramic insulators. Glass insulators have the characteristics of high mechanical strength, resistance to mechanical impact, good thermal and cold performance, long service life, excellent electrical performance, and lightning resistanceAnd when it is damaged during operation, its umbrella disc automatically breaks, greatly reducing the workload of insulation detection.

　　 High voltage line ceramic pull rod insulators are used on terminal tension and corner poles of overhead power lines of IOkV and below, for insulation and fixing of conductors. It can replace some butterfly porcelain insulators and disc-shaped suspension porcelain insulators.

　　③ Rod type porcelain insulators for electrified railway contact network

　　2) Low voltage line insulators

　　 ① Pin type, butterfly type, and shaft type porcelain insulators for low-voltage lines: Pin type porcelain insulators for low-voltage lines are used for insulation and fixing wires in overhead power lines below 1kV. Butterfly porcelain insulators are used as insulation and fixed conductors on the terminals, tension and corner poles of low-voltage power supply and distribution lines. Low voltage line shaft ceramic insulators are used as insulation and fixed conductors on the terminals, tension and corner poles of power distribution lines.

　　② Tensioning porcelain insulators for overhead power lines: used for balancing the tension on AC and DC overhead transmission and distribution lines, as well as communication lines, at corners or on large-span poles, for tensioning insulation and connection purposes.

　　③ Insulators for tram lines: used as insulation and tensioning conductors for tram lines or as insulation and support for conductive parts on trams and power stations.

　　④ Needle type porcelain insulators for communication lines: used for insulating and fixing wires in overhead communication lines. ⑤ Insulators for wiring: including drum insulators, porcelain clamps, and porcelain tubes. Used for low-voltage wiring. 3) High voltage power station insulators

　　① High voltage indoor post insulators for power stations: used for rated power frequency voltage 6& mdash; 35kV indoor power stations and substations.

　　Transportation precautions:

　　（1) Composite insulators should have good moisture-proof, anti vibration, anti rust, anti-theft and other protective measures to ensure the safe delivery of composite insulators to the site without damage due to the above reasons.

　　(2) Composite insulators with voltage levels of 330kV and above should be packaged in appropriately sized, rainproof, and rodent proof cylinders, and the end caps at both ends should be firm and reliable.

　　(3) The packaging of composite insulators should have sufficient strength to withstand handling during transportation, on-site storage, and installation.

　　(4) Suitable buffering measures should be installed inside the packaging tube to prevent damage or deformation during transportation and handling. All these materials should have chemical stability and waterproofness, and should not adhere to composite insulators or corrode them during outdoor storage.

　　(5) To ensure the safe arrival of goods at their destination, all packaging boxes should have correct, clear, and secure markings.
