TYPE 241 1.1 – 11kv

Semiconductive screened cable for general use to AS/NZS 1802. Type 241 cables are widely used for underground coal mining trailing and reeling applications requiring enhanced mechanical protection beyond light-duty constructions.

1.1/1.1 kV to 11/11 kV general purpose cable used for continuous miners, or feeder cables to pumps. Also commonly used for monorails supplying DCBs and longwalls. Typically, a more flexible cable for use is a semiconductive screen instead of a metal screen.

Znergy Type 241 and 241S constructions focus on improved sheath durability, stable screen geometry to resist migration, and balanced flexibility to extend service life without compromising handling.

USE WHEN: Medium to heavy trailing duty, moderate reeling, elevated abrasion exposure.

DO NOT USE WHEN: Extreme crush risk or heavy impact dominates continuously.

AS/NZS 1802

Fire retardant — self-extinguishing per AS/NZS 1802.

Flexible — designed for trailing and moderate reeling applications with repeated handling cycles.

Core: Metal: tinned copper, three core three earths plus central pilot.

Conductor separator tape: 1.1/1.1 kV – polyester where necessary. 3.3 kV and above – semiconductive screen.

Insulation: EPR (R-EP-90) core with durably printed core numbers at intervals less than 300 mm, on black semiconductive insulation screen for phase identification.

Screen: Semiconductive elastomer screen.

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.

Earth: Three semiconductive elastomer covered flexible earths, located in the interstices.

Sheath: Open weave reinforcement, under heavy duty HD-85-PCP.

Common failure modes in standard constructions include screen migration under torsional stress, sheath cracking from repeated dragging, and reduced service life when cables are underspecified for duty cycle.

• Underground coal mine trailing & reeling duties (medium to heavy)
• Continuous miners and longwall feeder cables
• Monorails supplying DCBs and longwall equipment
• Feeder cables to pumps, fans and auxiliary equipment Applications
• requiring semiconductive screen (more flexible than metal screen)
• Where Type 209 is underspecified for the mechanical duty cycle
