Designed for light to medium duty trailing applications where flexibility and flame retardance are critical. Type 209 cables are commonly used for portable and semi-mobile underground equipment where frequent movement occurs.
Znergy Type 209 cables are engineered with controlled conductor stranding and insulation systems selected to tolerate repeated flex cycles. Pilot core construction is stabilised to reduce fatigue-related failures, and sheath compounds are selected for improved abrasion resistance within the limits of flexible construction.
USE WHEN: Frequent movement, moderate mechanical stress, high flexibility required.
DO NOT USE WHEN: Sustained heavy dragging, high crush risk, or severe abrasion dominates.
Znergy\'s Type 209 is a premium flexible power cable engineered for the demanding environments of mining and heavy industry. Rated from 1.1/1.1 kV up to 11/11 kV, this cable is purpose-built for feeder connections between transformers and gate-end boxes, as well as power distribution to pumps, fans, crushers, and similar high-load equipment.
Where Type A or B feeder cables are typically specified, the Type 209 serves as a direct and fully compliant substitute — offering equivalent or superior performance with enhanced flexibility and resilience. It is equally suited to above-ground applications, including power supply to mobile and relocatable equipment.
The Type 209 is manufactured and tested in full compliance with the following Australian and New Zealand standards:

Composite screened cores with a single extensible pilot.
Core: Metal: tinned copper, three core plus central pilot.
Conductor separator tape: 1.1/1.1 kV – polyester. 3.3 kV and above – semiconductive tape.
Insulation: EPR (R-EP-90).
Insulation tape: 1.1/1.1 kV – proofed textile. 3.3 kV and above – semiconductive screen.
Screen: Composite screen (earth) of tinned annealed copper wire and polyester yarn. Core colours: red, white, blue braid tracers.
Pilot: Single, in centre of cable. Maximum DC resistance; 5.5 Ω/100m for power cores to 35mm2. 3 Ω/100m for power conductors above 35mm2.
Sheath: Heavy duty HD-85-PCP Sheath reinforcement is available upon request.
Common failure modes in misapplied Type 209 cables include insulation fatigue from excessive mechanical loading, pilot core breakage due to tight bend radii, and premature sheath wear where abrasion is underestimated.
