This article will explain the introduction and application of flexible fiberglass rods to you.
1. Flexible fiberglass rods are used as structural parts in motors and electrical appliances, and their requirements are quite different. Different flexible fiberglass rods can be selected according to their own insulation requirements, so that the customer can choose suitable products better!
2. Square bakelite rod, commonly known as pultruded fiberglass rod, is a round bar with high mechanical and dielectric properties formed by hot pressing of forming mold. It is suitable for insulating structural parts of motor and electrical equipment, and can be used in humid environment and transformer oil; It is generally used for lightning arrester or insulator spindle.
3. Density is greater than 2.0 g/ cm3;
4. Bending strength is less than 320Mpa;
5. Compressive strength is greater than or equal to 200Mpa;
6. Shear strength is greater than 32Mpa;
7. Dielectric constant is 3-6;
8. Dielectric loss factor (50 Hz) is greater than or equal to 0.02;
9. Volume resistivity 1. Greater than or equal to 1.0*10 to the 11th ohm in normal condition, greater than or equal to 1.0*10 to the 9th ohm when immersed;
10. Insulation resistance in parallel layer direction 1. It is greater than or equal to 1.0*10 ^ 11 ohms under normal condition, and greater than or equal to 1.0*10 ^ 9 ohms under water condition;
11. Surface voltage resistance (1 minute in air, spacing 30mm) 14 KV;
12. Vertical layer resistance voltage (in 90+-2 ° C transformer oil for 5 minutes) 18-20 KV;
13. Parallel layer voltage resistance (in transformer oil of 90+-2 ° C for 5 min, spacing 25mm);
14. Insulation resistance is greater than or equal to 5*10 ^ 4 omega;
15. Power frequency withstand voltage: Distance between oil chamber of on-load tap switch and ground (withstand voltage in transformer oil, 100mm. 5 mins). The interphase distance (according to customer's technical requirements) is greater than 85 KV.
16. Models and specifications can be customized according to requirements.
17. Square flexible fiberglass rods can choose a large cutting machine processing, round flexible fiberglass rods can choose milling machine processing!
18. Reinforced flexible insulation fiberglass rods can better meet the needs of high-end customers!
