Type 441.1 Class 2 Screened Mining Cable 1.1/1.1 kV

Type 441.1 Class 2 mining cable for 1.1 kV service

Type 441.1 Class 2 mining cable is a 1.1/1.1 kV screened cable for general mine use outside underground coal-mine applications, according to the supplied datasheet. It is a focused low-voltage product page rather than a catch-all Type 441 listing: the source gives one voltage designation, one Class 2 construction and its own area, diameter and mass tables.

The construction combines three flexible tinned-copper power cores, three interstitial earth cores and one central pilot. Power-core insulation is Class 2 EPR R-EP-90 with a semiconductive layer; the cores are laid over a semiconductive cradle. The earth cores are not insulated, and the assembly is completed by semiconductive elastomer bedding, an open-weave reinforcing braid and a heavy-duty elastomer outer sheath.

Selection should start with the 1.1 kV machine supply and the required conductor area, then move to the cable-entry, support and handling conditions. The datasheet records a 4.2 kV test voltage, but it does not provide current capacity, bend radius, pulling load or travel speed. Those details belong in the equipment-specific RFQ.

Type 441.1 Class 2 screened arrangement

This Type 441.1 variant uses a compact screened assembly with three power cores, interstitial earth cores and one central extensible pilot. The Class 2 designation and 1.1/1.1 kV rating should remain visible in every size cross-reference.

The supplied cross-section is placed here because the earth-core and pilot positions are part of the product identity. Termination and screening continuity must be checked against the machine design.

Type 441.1 Class 2 application boundary

The source describes Type 441.1 for general use in mines except underground coal mines, where screened cores and reinforcement are required. That boundary is important when this 1.1 kV product is compared with other mine-feeder families.

• General mine installations outside underground coal-mine service
• Underground or open mines needing screened cores and reinforcement, as stated in the source
• Mobile equipment cable routes where a three-earth/one-pilot arrangement is specified
• Confirm the machine voltage, cable-entry space, screening termination and mechanical handling before substitution

The sheet does not state water, oil or UV ratings or a minimum bending radius. Do not turn the application description into a broader environmental or mechanical guarantee.

Type 441.1 Class 2 Screened Mining Cable 1.1/1.1 kV technical data

The dimensional and electrical values below are transcribed from the supplied PDF for Type 441.1 Class 2 mining cable. The tables are retained by voltage, screen option or construction section as presented in the source. Source ordering codes are included where present in the extracted table; blank source cells are not assigned new values.

Use the relevant area, conductor dimensions, insulation or covering thickness, nominal diameter and mass together. The source does not create a universal current-capacity, bend-radius, pulling-load or travel-speed value for this product.

Type 441.1 Class 2 source references

This product is kept separate from the higher-voltage Type 441 Class 1 page because the source documents define different classes and voltage ranges.

Reference the exact Type 441.1 Class 2 designation in the RFQ and request the applicable inspection or test documentation with the cable schedule.
