Primary Leads

Shielded ignition systems require all wiring to be approved for hazardous locations. MOTORTECH manufactures a wide range of shielded primary leads that meet the CSA Class I; Division2; Group C/D; T4 requirements. A variety of leads is available to fit all common ignition coils and the MOTORTECH AlphaRail wiring rails. Heavy duty connectors (non cadmium plated) and a thick stainless steel braid with hydraulic ends will make this product live in a harsh environment.

Primary Leads

In addition to its conventional primary leads, MOTORTECH offers a new type of primary lead that is produced with a special wire. The new primary leads are compliant with CSA Class I, Division 2, Group D, and they offer a significantly higher flexibility than conventional leads, shielded with braided steel, while being highly resistant to all kinds of environmental conditions.

The multi-layer design of the wire is free of entrapped air and prevents the accumulation of condensed water which can result in primary voltage flash-overs. Several different configurations with durable 90-degrees and 180-degrees 2-pole and 3-pole connectors are available.

The oil and UV resistant multi-conductor wire is specially designed for shielded CSA certified primary leads.

It consists of a multi layer design:

Fine bare copper wire
PVC/Nylon insulation
Aluminum-plated foil and tinned copper braid
PVC jacket
Temperature range -40° C to +90° C (-40° F to +194° F)
This design ensures that no humidity can be trapped in the lead.

Primary Leads for AlphaRail Wiring Rails

For linking flange, integral or externally mounted ignition coils to its AlphaRail ignition wiring rails, MOTORTECH offers a special series of primary leads. Several different configurations are available to offer an individual solution for any application.

(1) 2 or 3 pole MIL style connectors as 90° or 180° type for ignition coil connection
(2) Primary leads available for shielded applications (Conventional or New Flex Style) or unshielded applications
(3) 2 pole MIL style connector as 90° or 180° type for wiring rail connection
