2491X to BS 6004 Cables

450/750V PVC Insulated, PVC Sheathed, Screened Controlling Cables (2 core)

RE-Y(St)Y (CU/PVC/OS/PVC 450/750V Class 5)

 

 

APPLICATION:

The Airprot cables unarmoured versions (Part 2 Type 1) are generally use for indoor installation and suitable for wet and damp areas. Generally used within industrial process manufacturing plants for communication, data and voice transmission signals and services, Also used for the interconnection of electrical equipment and instruments, typically in chemical or petrolchemical industry.

STANDARDS:

Basic design to BS 5308 Part 2 Type 1
