(N)7YAbl · (N)7YAvz · (N)7YAvs · (N)7YAvn
ETFE insulated wires with extended temperature range, 450/750 V
Application
(N)7YAbl · (N)7YAvz · (N)7YAvs · (N)7YAvn is an ETFE-insulated wire with extended temperature range 450/750 V and low and high temperature resistance. It is recommended for use in high-frequency and broad-band techniques, coaxial and microwave techniques, high information velocity with exact information transmission at the same time, chemical industry, furnace construction, brick works, and heating applicances.
Outstanding features
- high resistance against chemicals and solvents
- low and high temperature resistance
- good electrical insulating characteristics with low, nearly frequency-independent dielectric characteristics
- EAC approval
