Informations de base
Description du produit
|1. Measurement precision can be up to 0.1 and 0.2S grades.|
2. Primary coil has a through -type conducting rod structure with good dynamic and thermal stabilityy; its maximum thermal current can be up to 63kA/3s.
3. Secondary coil is fixed in an aluminum shielded-case by casting organic materials; secondary measurement and protection circuits can be safer and reliable.
4. Partical discharage test is carried out under power frequency test voltage. The result is better than the requirement of IEC.
5. Use the automatic vacuum drying treatment system produced by LEYBOLD in Germany. The dielectric dissipation factor of complete product tanδ is less than 0.4%.
6. External insulation uses a high-strength porcelain.
7. Secondary terminal box is a complete structure by casting the aluminum alloy; its sealing structure meets the requirement of IP55, which is dust proof, water proof and air permeable.
8. The materials of all components are cast alunimum or stainless steel, including the base, connection box, stainless steel expander and nameplate etc do not rust forever.
9. This product is free-maintenance.
