| Application |
BS5308 cables are used to
carry voice and data services, they also serve as the interconnection
between electrical equipment and instruments, particularly in
and around process plants, where transducer generated signals
are transmitted through to panels, controllers and other devices. |
| Standards |
BS5308 Part 1 Polyethylene Insulated Conductors |
| Conductor |
Plain annealed copper conductors complying
with BS6360 |
| Construction conductors |
Plain annealed copper conductors complying
with BS6360 |
| Insulation |
Polyethylene to BS6234 type 03 or XLPE
(Cross Linked Polyethylene) for LSZH cables. (LSZH cables are
generally to BS5308) |
| Pairing |
Two insulated conductors uniformly twisted
together with a lay not exceeding 100mm. |
| Pair identification - individually pair
screened cables |
One blue core and one black core in each
pair identified by a numbered pair screen isolation tape. (Collectively
Screened Pairs) Coloured, as per BS5308 PT1 |
| Pair screens - individually screened pairs |
Where individual pair screening is required,
an Aluminium/Polyester tape screen is applied to each pair,
Metallic side down and in continuous contact with a 0.5mm²
tinned copper drain wire |
| Pair screens - collectively screened cables |
For cables requiring a collective screen,
an Aluminium/Polyester tape screen is applied over the laid
up pairs metallic side down and in continuous contact with a
0.5mm² tinned copper drain wire. |
