EN 50288-7 STANDARDS PE Insulated, LSZH Sheathed & Overall Screened Instrumentation Cables (Single Pair)
RE-2Y(St)H 90°C / 300V

APPLICATION

The unarmoured LSZH sheathed cables are generally use for indoor installation and suitable for wet and damp areas. Generally, the cables are used within industrial process manufacturing plants for communication, data and voicetransmission signals and services. Also used for the interconnection of electrical equipment and instruments, the LSZH sheath can reduce toxic smoke and fume emission.

STANDARDS

Basic design to EN 50288-7

FIRE PERFORMANCE

Flame Retardance (Single Vertical Wire Test)

CABLE CONSTRUCTION

• Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
• Insulation: PE compound, EN 50290. 2-23.
• Pairs: Two insulated conductors uniformly twisted together with a lay not exceeding 100mm
• Binder tape: PETP transparent tape
• Overall Screen: Aluminium/polyester tape is applied over the laid up pairs metallic side down in contact with tinned copper drain wire, 0.5mm2
• Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH compound type SW2-SW4 as per BS 7655-2.6 can be offered.). UV resistance, hydrocarbon resistance, oil resistance, anti rodent and anti termite properties can be offered as option.

COLOUR CODE

Insulation: Black / White, continuously numbered on white core(1, 2..)for multipair.

Outer Sheath: Black or blue for intrinsically safe systems
