1 Scope
2 PfG 1169/08.2007 applies to flexible single-core cables (cords) for u at the DC-side of photovoltaic-systems with a maximum permissible voltage of DC 1,8 kV (conductor/conductor, non earthed system). The cables are suitable for u in safety class II.
It is permitted to connect the cables as multiple-construction.房地产销售管理系统
The cables are intended to operate at ambient temperature until 90°C

3 Terms and definitions
For the purpos of this document, following definitions apply.
3.1 Terms for test procedure
3.1.1
Type test (symbol T)
我的篮球梦Tests required to be made before supplying a type of cable covered by this standard on a general co
mmercial basis, in order to demonstrate satisfactory performance characteristics to meet the intended application. The tests are of such a nature that, after they have been made, they need not be repeated, unless changes are made in the cable materials or design or manufacturing process which might change the performance characteristics.
3.1.2
sample tests (symbol S)
Tests made on samples of completed cable or components taken from a completed cable, at a specified frequency, so as to verify that the finished product meets the specified requirements.
3.1.3
Routine tests (symbol R)
Tests made by the manufacturer on each manufactured length of cable to check that each length meets the specified requirements
3.2
Rated voltage
The rated voltage of the cable determines the construction and the tests of the cable with regard to the electrical properties.
The rated voltage is designated by two values of frequency voltage: U0/U in Volt
U0 rated power frequency voltage between conductor and earth (metallic screen of cable or ambient medium);
U rated power frequency voltage between two conductors of a multipole cable or of a system of single core cables.
The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is ud.
This requirement is applicable for both U o and U
The rated voltage between two conductors in a DC-system shall not exceed the 1,5 time value of rated voltage U of the cable, and the rated voltage between conductor and earth shall not exceed the 1,5 time value of rated voltage U o of the cable.
NOTE The operating voltage of a system may exceed is rated voltage permanent for 20%. A cable may be operated with a voltage which value is 20% higher than rated voltage under condition that the rated voltage is not less than the rated voltage of the system.
