2 PfG 1169/08 is a test specification of TÜV Rheinland for flexible single-core cables (cords) used on the d.c. side of PV systems, with a maximum permissible voltage of 1.8 kV d.c. between conductors in a non-earthed system (2 PfG 1169/08 Clause 1). Its foreword explains that it takes over the requirements of a draft by the DKE working group on PV cables, prepared for publication as a German pre-standard, and that it was to be used for testing PV cables only until that pre-standard appeared. For PV d.c. cabling the European standard is now EN 50618, which covers flexible single-core cables of the same kind under the code H1Z2Z2-K. Where a project calls for EN 50618, please see the H1Z2Z2-K EN 50618 page.

Cable Construction

Conductor: Single flexible conductor of class 5 to EN 60228, made of tinned wires (2 PfG 1169/08 Clause 4.3.1)
Separation layers: Optional over the conductor and between insulation and sheath (2 PfG 1169/08 Clauses 4.3.2 and 4.3.4)
Insulation: Extruded halogen-free compound, not thinner than 0.5 mm at any point (2 PfG 1169/08 Clause 4.3.3)
Sheath: Extruded halogen-free compound, not thinner than 0.5 mm at any point (2 PfG 1169/08 Clause 4.3.5)
Marking: Trademark, code designation PV1-F and cross section, repeated at intervals of not more than 550 mm (2 PfG 1169/08 Clause 4.3.8)

Electrical and Thermal Ratings

Item	Value
Rated voltage, a.c. (U₀/U)	0.6/1.0 kV
Rated voltage, d.c. (conductor to conductor, non-earthed system)	1.8 kV
Maximum voltage, a.c.	1.2 kV
Test voltage, 5 min	6.5 kV a.c. or 15 kV d.c.
Ambient temperature	−40 °C to +90 °C
Max. conductor temperature	120 °C
Short-circuit temperature	200 °C, 5 s

The d.c. rating of 1.8 kV applies between conductors of a non-earthed system with the circuit not under load (2 PfG 1169/08 Clause 4.2.1), and it is also the maximum permissible d.c. voltage of the cable (2 PfG 1169/08 Clause 1).

The current ratings in the TDS hold for an ambient temperature of 60 °C and a conductor temperature of 120 °C (2 PfG 1169/08 Clause 4.6); at other ambient temperatures they are multiplied by the factors in the TDS, and grouped cables are corrected as given in IEC 60364-5-52.

Typical Applications

Cabling on the d.c. side of PV systems, for use as set out in EN 60364-7-712
Equipment of safety class II
