Figure 8 Cables
Tinned copper cable is offered where possible. Tinning doesn't stop corrosion, but it slows it down significantly. Tinned cable is more acurately described as being copper cable electroplated with a nickel alloy. The cable is sold in metre lengths or by the spool (10% discount by the spool), pricing is per metre. The number in brackets at the end of the descriptor refers to the spool length usually available from our suppliers. Our cable is specified in terms of the cross sectional conductor areas. Many other standards are used worldwide, such as diameter, AWG (American Wire Guage) size or BS (Battery and Starter) ratings. Cable must be sized to ensure that the voltage drop over the full length of the run is kept withing acceptable limits. The voltage drop depends on the cross sectional area of the conductor, the current (Amperes) conducted, the length of the run and of course the voltage. Normally the voltage drop should not exceed 3%, although higher losses are sometimes accepted in situations where equipment is infrequently used or the loss in performance does not warrant running expensive and heavier cable. The voltage drop should under no circumstances exceed 10%. A current rating for a given cable should therefore only ever be viewed as a guideline. For cable size selection, refer to the additional information on voltage drop tables and cable size equivalents. Figure eight cable consists of two isolated cables moulded together, ideal for long cable runs to navigation lights, general lighting, bilge pumps etc. The 2mmﾲ cable can be used for general purpose wiring for lights, small bilge pumps etc. The 1mmﾲ cable is suitable as speaker cable and running very light loads. It can be used for LED lighting due to the low current drawn by these lights. |

Foil Shielded Twisted Pair Instrument Cable
Twisted pair cabling is a form of wiring in which two conductors are wound together for the purposes of canceling out electromagnetic crosstalk between neighbouring pairs. Twisting wires decreases interference because the loop area between the wires is reduced. In balanced pair operation, the two wires typically carry equal and opposite signals which are combined by addition at the destination. The common-mode noise from the two wires cancel each other in this addition because the two wires have similar amounts of EMI that are 180 degrees out of phase. |
