PREFABRICATED UNSCREENED PRIMARY LEADS AND EXTENSION CORDS
Our unscreened primary cables comprise a TPE insulated one core cable with a bare copper
conductor (19 strands/min 6 mm2).
These cables are manufactured in accordance with the specifications FAA L-824
(MIL-C-3432 or ICEA S-66-524) or MIL-C-4921, in general.
Nominal voltage is 5 000 V.
Prefabricated, molded primary leads, with the desired cable length
- Molded on 6 mm², 5 kV cable. Upon special request AWG 8 (8.3 mm2) is also available
- KDCP510.x.x: the plug connector is FAA L-823 Style 2
- KDCR510.x.x: the receptacle is FAA L-823 Style 9
- With KDCP510 and KDCR510, the other cable end is free
The cable length is given in centimeters as a suffix in the article number, KDC 510.8.xx. (for example, KDCP510.8.60 is a Style 2 connector with a 60 cm lead)
Prefabricated unscreened primary leads


KDCE510.x.x: Extension cable with a plug and receptacle.
PREFABRICATED SECONDARY LEADS AND EXTENSION CORDS
The leads are available with two-core cables or with two single core wires. The latter even with higher temperature resistant wires.

Cable information:
Secondary two core cables are EPR–insulated and TPE–sheathed with stranded bare copper conductor. Cables are in accordance with the specifications FAA L-824 (MIL-C-3432 or ICEA S- 66-524) or MIL-C-4921 in general. Possible cross-sections are 1.5 mm2 (OD 8,5mm), 2.5 mm2 (OD 10,0 mm) and 4 mm2 (OD 12 mm). Nominal voltage is 600V. Bending radius is 5D.
Extension cords:
The types above can be made to a specific length, with plug on one end and receptacle on the other. For example KDCE501.4.3000 (4 mm2 and 30 m).

CABLE AND WIRE INFORMATION
The secondary wire is bare copper, class 5 (IEC 60228). The core insulation is a special EPR compound. The outer sheath is a halogen free TPR compound (IEC60754-2/ EN 50267-2-3).
The operating voltage is 0.6/1kV, with a temperature range of -40 up to +120ºC. The short-circuited short-term temperature resistance is 300ºC (570°F) and the bending radius 5xD.
