Construction

Layer by layer

In Type SHD-CGC (2 kV & 5 kV), three EPR-insulated phase cores (each with a semi-conducting strand shield and tinned-copper + colour-coded nylon braid shield) are cabled around a central 16 AWG yellow polypropylene-insulated ground-check conductor, with three bare tinned copper grounding conductors in the outer interstices and integral torsion-resistant fill under a reinforced mold-cured CPE jacket. In Type SHD Flat 3C (2 kV), three shielded phase cores lie parallel with two 3 AWG grounding conductors between them.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the difference between Type SHD-CGC, Type SHD-GC and Type SHD?
All three are individually phase-shielded trailing cables to ICEA S-75-381 / NEMA WC 58, but their grounding and pilot geometry differ. Type SHD-GC places two grounding conductors in two outer interstices and an 8 or 6 AWG ground-check pilot in the third interstice. Type SHD-CGC ('Center Ground Check') places a high-strength 16 AWG yellow polypropylene-insulated ground-check pilot in the geometric center of the three phase cores and distributes three grounding conductors symmetrically in all three outer interstices — preventing pilot breakage under torsion in longwall cable handlers. Plain Type SHD (such as Type SHD Flat 3C 2 kV) includes grounding conductors and phase shields but omits the ground-check pilot.
Why does Type SHD-CGC use a 16 AWG polypropylene-insulated center ground-check conductor?
Under MSHA 30 CFR § 75.804(a), underground coal trailing cables are permitted to use a center ground-check conductor not smaller than 16 AWG insulated with polypropylene rather than a larger interstitial pilot. Placing the 16 AWG pilot along the neutral axis of the cable eliminates alternating tensile and compressive strain as the cable bends and twists through longwall Bretby chains.
How are the individual phase shields identified in Type SHD-CGC?
Each EPR-insulated phase conductor is screened with a composite braid combining tinned copper strands (for fault-current and capacitive-charging drainage) and colour-coded nylon yarn (Black, White, Red) so electricians can identify phases without stripping back the metallic screen.
When is Type SHD Flat 3C (2 kV) specified instead of round Type SHD-CGC?
Type SHD Flat 3C (such as 3 × 2/0 AWG + 2 × 3 AWG grounds, 1.205 × 2.970 in / 30.6 × 75.4 mm) is specified for low-seam 2,000 V continuous miners and shuttle-fed face equipment where the machine entry gland and level-wind guide require a low-profile flat cable and the protection scheme does not use a separate pilot wire.
