1 Scope
These cables are for installation in indoor Residential Cabling Systems. They are specified
up to 1 000 MHz. Their design is based on the requirements of the EN 50290-2-1. They are
specifically designed for cabling in residential environment supporting ICT and BCT
applications. (Telephone, Computer and TV services). This specification defines the
constructional details as well as the specific performances of the cables.
Unless otherwise specified, all cables covered by this standard may be subjected to
voltages not more than 300 V a.c. or 450 V d.c. and shall meet the essential requirements of
the low voltage directive. Due to current limitation related to the conductor cross sectional
area, they are not intended for direct connection to mains electricity supply. The maximum
current rating per conductor is less than or equal to 3 A/mm² unless otherwise specified in
the relevant detail specification.

4 Cable construction
4.1 Conductors
4.1.1 Conductor construction
According to 4.1 of EN 50290-2-1.
4.1.2 Conductor Type
According to clause 4.1.1 of EN 50290-2-1, the conductor is a solid wire of annealed copper
with a minimum diameter of 0,5 mm (diameters larger than 0,8 mm could cause
connectorisation problems).
NOTE Diameter < 0,5 mm and > 0,65 mm may cause problems with connecting hardware.
4.2 Insulation
4.2.1 Insulation material
The insulation of the conductor shall be polyethylene in accordance with EN 50290-2-23.
