Conductor:
• Tinned flexible circular copper, 0.75, 1.0 & 1.5 sqmm (BS6360 class 5)
• Tinned stranded circular copper, 2.5 sqmm (BS 6360, class 2)

Insulation: EP-rubber, GP4 to BS 7655: section 1.2

Pair/Triple/Quad twisting / lay up:
• Colour coded cores twisted together to form a pair, triple or quad, which is individually screened with aluminium backed polyester tape with a tinned copper drain wire. Each pair, triple or quad is wrapped with polyester tape to prevent electrical contact with adjacent pairs, triples or quads.
• Individually shielded pairs, triples or quads are laid up in concentric layers and wrapped with a PETP tape.
• Pairs, triples, or quads are identified by numbers printed directly on the insulated conducors.

Inner Covering: Flame retardant and halogen-free thermoset compound

Tape Over Inner Covering: PET tape + rubberized Polyamide tape

Armour/Screen: Galvanized steel wire braid

Tape Over Armour / Screen: PET tape  + rubberised Polyamide tape

Outer Sheath: Flame retardant, halogen-free, enhanced oil-resisting thermoset compound (LSF), SW4 to BS 7655 section 2.6

Marking Text: "metre mark" "year" "DRAKA" "RFCU(I)" "UKOOA code" "150/250V" "number of pair, triples or quads" "conductor size" "BS6883" "IEC60332-3-22" (marking may differ on cable actually supplied)

Outer Sheath Colour: Grey or Blue

Core Identification:
• Pair - Black-White, numbered 1-1, 2-2, 3-3....
