This cable calculator is to be used as a guide only; the cable sizes are worked out using information given from your input, accurate values are essential to give you the correct cable size. The user is to ensure the type of cable is suited to environment and conditions the cable will be exposed to.
This cable calculator is set for Installation method C (Clipped Direct), for cable types BS5467 and BS6724 SWA (Steel wire armoured cable) and is based on the voltage drop selected at 230V single phase and 400V three phase.

General Information & Technical Specifications - YY Cable
How is YY Cable constructed?
YY Cable Conductor : Class 5 plain stranded flexible copper conductors to BS EN 60228:2005 (previously BS6360), VDE0295
YY Cable Insulation : YY PVC: PVC (Polyvinyl Chloride) Type YI2, YY Cable LS0H : XLPE (Cross-Linked Polyethylene)
YY Cable Sheath : YY PVC: PVC (Polyvinyl Chloride) Type YM2 , YY LS0H: LSZH (Low Smoke Zero Halogen)
By what other names is YY Cable known?
YY Cable is also referred to as Instrumentation Cable, Unscreened, Flexible or Unshielded Control Cable and YY Control Flex.
Which industries use YY Cable?
Suitable for use in a number of industries, YY Cable is found frequently in building and construction, rail and transport infrastructure, and automation and process control.
YY Cable is designed for use on assembly and production lines, conveyors, in machine tool manufacture and in computer units. This unscreened YY Cable works well as interconnecting cable for measuring, controlling or regulation in signal and control equipment. Its flexible layers make YY Cable ideal for linking fixed and mobile equipment – as well as projects involving light mechanical stress and fixed installations.
With the right protection (such as keeping it out of direct sunlight), YY Cable is useful in outdoor projects, although it is mostly found in either dry or moist indoor environments.
What is YY Cable?
YY Cable is a flexible multi-core cable with class 5 stranded copper conductors, PVC insulation and a grey PVC sheath that is manufactured generally to BS6500 and VDE0250 standards.
There is a Low Smoke Zero Halogen – or LS0H – version of this versatile YY Cable. The LS0H YY Cable has a similar construction – it simply uses XLPE insulation and a grey LS0H sheath in place of PVC layers.
When would I need to use LS0H YY Cable?
If installation is in a public building, such as a school, office or hospital, LS0H YY Cable should be used. When exposed to fire, the cable’s LS0H sheath emits very low levels of smoke and non-toxic levels of halogen gas (typically under 0.5% HCl emission). LS0H may also be referred to as LSHF (Low Smoke Halogen Free), 0HLS (Zero Halogen Low Smoke), LSZH (Low Smoke Zero Halogen) or HFFR (Halogen Free Flame Retardant).
