Composite Railway Insulator

Types: Long rod composite insulator, tension & suspension insulator, line post, station post/busbar support insulator Composite insulator consists of three parts: Fiberglass core: ECR End fitting: Hot-dip galvanized forged steel and casting steel. Silicone rubber: HTV VOLTAGE RATING & STRENGTH RANGE 11kV up to 500kV. 40kN up to 300kN long rod type, 4kN up to 20kN post type. STANDARD TRONCO ELECTRIC insulators complied with the standard of IEC 61109 & IEC 61952 ADVANTAGES The use of composite insulators in place of traditional porcelain and glass insulators for line insulation has become widespread in the last 20 years. High temperature vulcanized (HTV) silicone rubber is dominating for transmission voltages. Lighter weight Lower cost Easier handling Better resistance to damage from vandals Superior contamination performance APPLICATION Long rod insulators are used for suspension and tension towers for high voltage grids and railway grids. Composite post insulators are used for disconnector, switchgear and substation works. Tronco Electric can also make the design and supply the insulator strings.

Railway composite insulators are a critical component in ensuring the safety and operational efficiency of railway systems. These insulators are specifically designed to provide a durable and reliable means of securing and isolating electrically charged rails from each other and the rest of the railway infrastructure. One of the leading brands of railway section insulator on the market is YF POWER, which offers a range of high-quality insulators that are designed to meet the stringent requirements of modern railway systems. Their railway telegraph insulators are made from durable materials that are resistant to wear and tear, heat, and other environmental factors that can cause damage and impact performance. YF POWER's commitment to quality and safety has earned them a reputation as a trusted and reliable supplier of rail insulators for railways around the world. Rail Insulator's Role in the Fastening Railway railroad insulators for sale play a critical role in fastening rail systems by providing electrical insulation between the rails, preventing the flow of electric currents between the rails, and ensuring the safety and reliable functioning of the railway system. These insulators are used to secure and isolate the electrically charged rails from each other and the rest of the railway infrastructure. The rail fastening system ensures proper alignment, stability, and load-bearing capacity of the tracks, while rail insulators provide corrosion resistance, long life, and excellent electrical insulation.

The railway insulator is an insulator product suitable for electrified railway tunnels with complex operating conditions. It is installed between steel rail and tie plate, for adjusting rail gauge and electrically insulating railroad rails, rail clips and rail bolts from the interior of a concrete sleeper. It can effectively prevent pollution flashover accidents and reduce the workload of cleaning and maintenance. Due to its small size, especially when the tunnel clearance is small, it is irreplaceable for ceramic insulator and glass insulators. Why insulated Rails are main parts of the rail tracks. They lead the train and transfer the pressure of the wheels to the sleepers. It must have a continuous smooth surface with minimum resistance. Currently in the electrified railways or automatic block zone the two rails double as signal lines of track circuits and loop line for locomotive traction. So rails must be insulated in case of stray current interference. Usually insulators and insulated rail joints are used in rail tracks. What are the types of railway insulators The following is the classification method of railway insulators: 1. Classification by structure Insulators are divided into: column (post) insulators, suspension insulators, pin insulators, butterfly insulators, tension insulators, anti-fouling insulators and bushing insulators. In addition, the cross arm can be regarded as a generalized insulator. 2. According to different functions It is divided into ordinary insulators and anti-fouling insulators. With years of experience designing and manufacturing railway insulators, has developed a new concept to improve safety and performance while optimizing cost considerations for our customers. is willing to cooperate with colleagues from all over the world and customers in the wider power field.
