ZCO3 & ZCO3-SH Main Signalling Cables (AC Electrifi ed High Speed Lines)

ZCO3 & ZCO3-SH Main Signalling Cables (AC Electrifi ed High Speed Lines)

Application

The cables are designed for connection between traffi c control centers and equipment shelters along the

trackside. The cables are specially designed to give good induction protection (R.F=0.21 at inductive voltage

100V/km) and are suitable for installation in high speed railway lines electrifi ed at 25KV ac.

Standards

SNCF CT 445

NF F 55-698

Construction

Conductors: Solid annealed copper, 1.0 mm² nominal cross section area.

Insulation: Solid polyethylene.

Cabling Element: Four conductors are twisted to form a quad.

Stranding: Quads are helically stranded to get the cable core.

Core Wrapping: Plastic tape(s) with overlapping.

Inner Sheath: Low density polyethylene. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).

Electrostatic Shield: Corrugated copper tape.

Intermediate Sheath: Low density polyethylene. LSZH FR option can be offered upon request to NF C 32 070.2.2

(C1).

Electromagnetic Shield: Two helically applied steel tapes (0.5mm).

Outer Sheath: PE/PVC compound. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).

Remarks: ZCO3: PE/PVC Sheath; ZCO3-SH: LSZH Sheath.
