90C rubber cable

16 Min Read
The AS/NZS 1802 Type 241 3x35mm² 1.1kV mining cable has a total weight of approximately 2,980 kilograms per kilometer, with copper content contributing roughly 1,500 kilograms per kilometer of that total. This cable has a 43.1 millimeter nominal outer diameter (tolerance range 41.5–44.5mm), carries an ampacity rating of 147 amperes in free air at 90°C conductor temperature, and is constructed from three 35mm² power conductors, three 16mm² interstitial grounding conductors, and one 16mm² central extensible pilot conductor (the latter typically used for remote control signaling in mining equipment). The cable is built to AS/NZS 1802 standard using EPR (ethylene propylene rubber) insulation and heavy-duty HD-85-PCP (polychloroprene) outer sheath, making it ideally suited for the extreme mechanical and thermal stresses of underground coal mining trailing cable applications—continuous miners, pump power supplies, and general mining equipment feeder systems. However, this specification applies exclusively to authentic AS/NZS 1802 Type 241 cables. Understanding this distinction is critical because many engineers and procurement teams encounter confusion when they search for "Olex Type 241" or "Versolex Type 241 equivalent," terms that conflate two fundamentally different product families with completely different material systems, standards, and field applications.

The Type W 4/C 2/0 AWG 2000V portable power cable features a heavy-duty CPE (chlorinated polyethylene) outer jacket that demonstrates exceptional resistance to both ozone and ultraviolet radiation across the typical operating life of outdoor industrial equipment. The cable meets MSHA requirements and passes ASTM D1149 ozone resistance testing, demonstrating no cracking or surface crazing when exposed to 50 parts-per-hundred-million (pphm) of ozone concentration for extended periods. The cable's UV resistance performance, when evaluated according to ASTM G154 accelerated UV aging procedures using UVA-340 lamps at 60°C for 1,000 hours of exposure, results in retention of approximately 80–90% of original tensile strength and maintains mechanical flexibility adequate for normal cable handling and deployment. This performance level, combined with the inherent flame retardant properties of the CPE compound formulation, means that Type W cable can remain in outdoor service for extended periods—typically 5 to 10 years of continuous or frequent outdoor exposure—without experiencing the surface cracking, brittleness, or loss of mechanical properties that would render the cable unsafe or unsuitable for reeling operations. The black color of the CPE formulation, while primarily selected for aesthetic reasons in industrial equipment, also serves a secondary protective function by absorbing and dissipating ultraviolet radiation rather than transmitting it to the inner EPR insulation layers. Understanding how the CPE jacket maintains its protective properties under outdoor exposure requires appreciation for both the chemistry of weathering processes and the engineering of additive packages that extend the cable's useful service life far beyond what conventional rubber compounds could achieve.
