CSA Type SHD-BGC, SHD-R and SHD-SP Shielded Mining Cable

Canadian open-pit oil-sands shovels, walking draglines, mobile crushers and underground hard-rock or potash mines specify CSA C22.2 No. 96 shielded portable power cables tailored to distinct ground-check and mechanical reeling duties. Whereas standard US ICEA Type SHD-GC uses an unshielded insulated ground-check core, the Canadian CSA C22.2 No. 96 family defines Type SHD-BGC, Type SHD-R and Type SHD-SP / Type SHD-GC-SP across 2 kV, 5 kV, 8 kV, 15 kV, 25 kV and 35 kV voltage ratings.

Type SHD-BGC incorporates a braided tinned-copper ground-check conductor (BGC) concentrically applied over an insulated pilot core so rock-crush impact immediately triggers the ground-fault monitor before phase-to-ground contact occurs. Type SHD-R adds an open-weave high-tenacity synthetic anti-torsion braid locked between dual thermoset CPE jackets for high-tension monospiral and level-wind cable reels on stacker-reclaimers and electric shovels.

Type SHD-SP and Type SHD-GC-SP replace metallic phase braid shields with a heavy-duty semi-conductive polymeric phase screen over the 90 C EPR insulation, eliminating broken metallic shield strands that can puncture insulation during severe flexing and simplifying field splicing. All variants are engineered for -40 C cold-bend/cold-impact performance and FT1/FT4 flame retardance.

CSA Type SHD-BGC, SHD-R and SHD-SP Shielded Mining Cable Construction & Layer Breakdown

The representative horizontal sample illustrates the CSA C22.2 No. 96 Type SHD-BGC 5 kV construction, showing three flexible rope-lay tinned copper power cores with triple-extruded EPR dielectric and tinned-copper/textile composite phase shields, two uninsulated interstitial grounding conductors, one yellow EPR pilot core with a concentric braided tinned-copper ground-check shield (BGC) and a reinforced two-layer -40 C thermoset CPE jacket.

CSA Type SHD-BGC, SHD-R and SHD-SP Designation Breakdown (CSA C22.2 No. 96)

• CSA C22.2 No. 96: Canadian Standards Association standard for portable power cables including arctic -40 °C cold-impact and FT1/FT4 flame compliance
• SHD: Shielded heavy-duty portable trailing cable with individual metallic phase shields over 90 °C EPR power conductors
• BGC (SHD-BGC): Braided Ground-Check — concentric tinned-copper braid shield applied directly over the insulated yellow ground-check pilot conductor (2 kV to 15 kV)
• R (SHD-R): Reeling service — anti-torsion synthetic reinforcing braid between dual CPE jackets plus flexible metallic braid phase shields for monospiral/cylindrical drums (5 kV to 35 kV)
• SP / GC-SP (SHD-SP): Semi-Conductive Polymeric phase screen — non-metallic flexible stress-control screen eliminating metallic braid strand fatigue on tight-bend equipment (5 kV to 15 kV)

CSA Type SHD-BGC, SHD-R and SHD-SP Trailing & Reeling Mining Applications

Select CSA Type SHD-BGC, Type SHD-R or Type SHD-SP / SHD-GC-SP according to provincial Canadian mine code requirements, reeling drum tension and field-splicing practices.

• Electric rope shovels, hydraulic face shovels and walking draglines in Canadian oil sands, open-pit coal, iron-ore and copper mines operating from 5 kV to 35 kV (Type SHD-BGC).
• Motorized cable-reel shovels, mobile hopper cars, bucket-wheel reclaimers and shiploaders requiring torsion-free drum reeling under CSA C22.2 No. 96 (Type SHD-R).
• High-flexibility trailing feeders and mobile substations where semi-conductive polymeric phase screens eliminate metallic braid fatigue and speed up field vulcanized splices (Type SHD-SP / SHD-GC-SP).
• Sub-zero Arctic and boreal open-pit or underground mining distributions requiring -40 C cold-bend and FT1/FT4 flame compliance.

CSA Type SHD-BGC, SHD-R and SHD-SP vs SHD-GC & SHD-CGC Selection Matrix

Specify CSA Type SHD-BGC when Canadian provincial mine codes require a concentrically screened ground-check pilot, SHD-R for tensioned cable reels, or SHD-SP where tight flexing causes metallic braid fatigue.

CSA Type SHD-BGC, SHD-R and SHD-SP Shielded Mining Cable Engineering FAQ

What is the difference between CSA Type SHD-BGC, SHD-R and SHD-SP?

All three are manufactured to CSA C22.2 No. 96 with 90 °C EPR insulation and -40 °C cold-impact CPE jackets. Type SHD-BGC (2 kV to 15 kV) features a concentric tinned-copper braid shield over the yellow ground-check pilot conductor for fail-safe pilot fault detection. Type SHD-R (5 kV to 35 kV) adds an anti-torsion synthetic reinforcing braid between dual CPE jackets for motorized reeling drums. Type SHD-SP / SHD-GC-SP (5 kV to 15 kV) replaces the metallic phase braid with a flexible semi-conductive polymeric phase screen to eliminate wire-strand fatigue in tight-radius underground flexing.

Why do Canadian mines specify a braided ground-check (BGC) pilot conductor?

In CSA Type SHD-BGC cables, the concentric copper braid over the insulated 8 AWG or 6 AWG pilot core is tied to ground. If rock crushing or mechanical pinch penetrates the pilot insulation before reaching a phase shield, the pilot conductor immediately contacts its concentric ground braid and trips the ground-check monitor relay at the feeder breaker.

Are CSA Type SHD-BGC and SHD-R cables tested for -40 °C arctic operation?

Yes. Every CSA C22.2 No. 96 Type SHD-BGC, SHD-R and SHD-SP cable is compounded and tested for -40 °C cold-bend and -40 °C cold-impact endurance alongside FT1 / FT4 and MSHA flame-retardant performance for year-round Canadian open-pit and underground operations.
