Security Cable Standards BS4737-3.30:2015

- Oct 15, 2018-

Over the past few years the UK security industry has been an increase in the number of Substandard security cables come in the market, these cables have caused some security systems case failures. So the BSI has introduced a new cable standard, BS4737-3.30:2015, which come into force from 1st April 2016, this replaces the 1986 version.

The detailed description as below from the standard. 

Type 1 - Cable with a Max resistance of 100 Ohms/km and LSZH insulation and sheathing. 

Type 2 - Cable with a Max resistance of 100 Ohms/km and PVC insulation and sheathing. 

Type 3 – Cable with a Max resistance of 155 Ohms/km and PVC insulation and sheathing.

All cables must be clearly labelled to show whether they are Type 1, 2 or 3 and must show the resistance value and the number of strands of the cable.


This standard gives installers a clear indication of the cable quality what they are using.

By using this standard to identify what type of cables should be used for particular system and this can prevent installers from being able to offer cheaper prices by using Sub standard cables, and ensure that only such cable can be used in the security cable installations.
