As a professional ceramic insulator supplier, offer different kinds of Station Post Insulator for Substation, Line Post Insulator, disc suspension insulator, etc. Ceramic Insulators are manufactured in various sizes and also as per customers requirement.
What is a ceramic insulator
Ceramic insulators are ceramic materials used to insulate electrically-conductive materials or temperature-controlled enclosures. In the context of electrical insulation, ceramic insulators are usually limited to the insulation of electrically conductive materials on an industrial or municipal scale.
Advantage
Ceramic insulators have good chemical and thermal stability, almost no aging deterioration, and have good electrical and mechanical properties.
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.
offers the most comprehensive range of porcelain line post insulator up to highest AC and DC system voltages with the most progressive technology, engineering and life time. Short production time, tighter tolerances, flexible design, extra-high mechanical strength and extended creepage distances are possible by isostatic process.
Ceramic Post Insulator Application:
Used for insulating and fixing wires in high voltage overhead transmission and distribution lines;
Advantage:
1.Solid and puncture-proof: Being in an atmospheric space and exposed to pollution, rain, and other natural phenomena make them at risk of being damaged due to punctures.
2.Flexible creepage distance: The post insulators should have a reasonable creepage distance that will not endanger the integrity of the insulating path. This distance shields against tracking.
3.High mechanical strength: Post insulators are exposed to compressive, torsional and bending forces on a daily basis. Therefore, the insulator must have high mechanical properties to overcome these forces, otherwise it will just collapse and be more expensive to replace.
Ceramic insulator has good chemical and thermal stability, almost no aging deterioration, and has good electrical and mechanical properties
Applicable Standard: IEC, GB, BS, ANSI, AS or Customer's requirement;
