XT Unarmoured Instrumentation to IEC 60092-376

XT Instrumentation marine cables were originally designed as a lightweight ship wiring cable. They have become popular throughout the petrochemical and process control industries due to their low smoke, low gas generation and increased flame retardant properties. XT-C offers collective foil screening whilst XT-I includes an additional foil screen around each pair to prevent crosstalk.
