Application fit

Is BS 6708 Type 43 Drill Cable right for your machine?

Short-lay extra-flexible screened trailing cable to BS 6708 Type 43 (125 V / 250 V) for hand-held and boom-mounted underground coal and rock drills.

Drilling jumbo & rotary mast feed

Suitable

Primary duty — short-lay core geometry absorbs severe twisting and flexing at rotary rock drills.

Trailing & towing

Suitable

Dragged across wet, rough heading floors between drill transformer panel and face.

Immersion & wet locations

Suitable

Heavy polychloroprene sheath resists flush water, rock dust and hydraulic oil.

Motorised monospiral reel

Not suitable

Short-lay drill cable elongates under high drum tension; do not use on crane reels.

Use (N)SHTÖU Reeling

Fixed installation

Not suitable

Dedicated low-voltage flexible drill lead, not a long-distance roadway feeder.

Construction

Layer by layer

Five equal 6 mm² (84/0.30 mm) Class 5 tinned copper conductors—3 phase, 1 earth and 1 pilot—each insulated with 1.00 mm EPR and wrapped with coloured textile identification tape, are laid up around a profiled semiconducting elastomeric cradle without contacting each other, enclosed in a 1.5 mm conducting elastomeric inner sheath/bedding and protected by a 2.5 mm heavy-duty black chloroprene (PCP) outer sheath.

FAQ

Questions engineers ask first

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

What is the difference between BS 6708 Type 43 and Type 44 drilling machine cables?
Both are 72/125 V (125/72 V) 5×6 mm² cables for handheld coal and stone drills. Type 43 uses an all-elastomeric earth-leakage screening system—a semiconducting centre cradle plus a 1.5 mm conducting elastomeric inner sheath—so there are no metallic screen wires that can fatigue under constant twisting. Type 44 uses individual composite tinned-copper/nylon braided screens (11 mm² total screen CSA) over the three phase cores.
Why is the rated voltage stated as 72/125 V (or 125/72 V)?
Under UK coal-mining safety regulations and BS 6708, handheld rotary drilling machines operate from a step-down drill transformer at 125 V phase-to-phase (72 V phase-to-earth) with sensitive earth-fault and pilot-core interlock protection.
Why is the maximum DC resistance 3.48 Ω/km instead of the standard 3.39 Ω/km for 6 mm² tinned copper?
Handheld drill cables use a short-pitch core lay to maximize torsional flexibility and kink resistance when dragged and coiled manually at the coalface, which slightly increases helical conductor length per kilometre of cable.
What are the overall diameter and weight of BS 6708 Type 43 5×6 mm²?
BS 6708 Type 43 5×6 mm² has a minimum overall diameter of 24.8 mm, a maximum overall diameter of 26.8 mm, a minimum bending radius of 268 mm (10 × OD), and an approximate cable mass of 1,020 kg/km (including 150 kg/km copper).
