High Voltage Railway Post Insulator
Product
Railway Insulators are important components of railway
infrastructure that are used to isolate electrical conductors from
their supporting structures. These insulators prevent the flow of
electric current between the conductor and the structure, thereby
ensuring the safety and reliability of railway operations.
Railway insulators are typically made of materials that are
non-conductive and have high electrical resistance, such as
porcelain, glass, or polymer materials. Porcelain insulators are
the most commonly used type of insulators in railway applications
due to their high mechanical strength, excellent electrical
insulation properties, and resistance to environmental degradation.
1. Polymer Insulator Character
1.1 High mechanical strength;
1.2 Good performance of hydrophobicity and anti-pollution;
1.3 Excellent electrical Performance;
1.4 Small volume and light weight
2. TID polymer Insulator Character and Advantage:
2.1 We adopt the advanced injection producing technology for
housing and the design of the shed adopt unique aerodynamics
principle.
2.2 Good Raw material :
We use HTV silicone rubber which hydrophobicity can reach to HC1
level
We use hot dip Galvanizing steel fitting ,the thickness of the zinc
more than 86 μm.
We use ECR rod as the core which is high acid resistant. 7200Hr
testing passed .
2.3 Special marking design.
We use the double seal design between the rubber and the fitting.
We can mark your logo on the fitting or rubber.
2.4 Excellent Manufacture Technology:
Perfect match between fitting and rod
Perfect bound between silicone rubber and the rod.
