PE Insulated & LSZH Sheathed Cables to CW 1600

Application

The cables are similar in design and application to CW 1308, but with Low Smoke Halogen Free cores and sheath. CW 1600 has the added advantage of an Aluminium/Polyester foil screen and drain wire. A fire barrier tape is included on cable with more than 6 pairs. The cables are used for the internal wiring of building when the need to protect people and equipment from smoke and fumes is paramount. The cables are designed to handle low frequency signals for short range applications and intended to be terminated in insulation displacement connectors (IDC).

Standards

• CW 1600

Construction

Conductors

Insulation
Solid polyethylene as per BS 6234/IEC 60708

Twisted Pairs
Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk

Cabling Element
Twisted Pairs/Triples/Quads

Cable Core Assembly
There are two modes of construction: layer for general use, including two cables for installation in customer's premises where a good appearance is required; and unit of 20 pairs which includes an insulated earth conductor of 1.38mm, for use with customer distribution scheme.

Core Wrapping
Cable containing more than 12 wires have a polyester tape applied over the cable core prior to sheathing.

Screen
A 24μ aluminium polyester foil shield can be provided for fully enclosing the core with an overlap

Fire Barrier Tape
Mica glass tape is included in cable with more than 6 pairs for achieving the required fire properties

Sheath
LSZH compound. Grey, White, Cream or Black colours are available for options

Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal

Drain Wire
A solid tinned 0.5mm earth/continuity wire shall be laid longitudinally
