Cross-linked cable silicone rubber GIS (dry type) terminal
Power Cable and Accessory
64KV/100KV Cross-linked cable silicone rubber GIS (dry type) terminal is a fully prefabricated oil-free constant force spring pressing dry structure and meets requirements in IEC8591999 standard;
1. 64KV/100KV Cross-linked cable silicone rubber GIS (dry
type) terminal is a fully prefabricated oil-free constant force spring pressing
dry structure and meets requirements in IEC8591999 standard.
2. Spring propeller structure pushes
the silicone rubber stress cone to closely contact with the inner wall of the
epoxy sleeve, ensuring no clearance between two components as well as even
interface.
3. The contacts use band type button
contacts, by combining with switches and transformer and other HV devices to
adjust conductor drawout structure with excellent contact performance and
reliable conducting performance; the metal aluminum shell design is adopted and
the shell is reliably grounded to effective prevent creepage, with strong
environmental adaptability, safe product installation and good protection
performance.
4. Flexible and easy site installation.
Each performance index of the product reaches or exceeds requirements in GB11017-2002.
