WORLDWIDE ENGINEERING STANDARDS

General Specification

GMW15626

Single-Core Stranded ISO Cable

1 Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. 1.1 Purpose. This standard specifies the dimension, test methods, and requirements for single-core cables. The standard is based upon and refers to ISO 6722-1. 1.2 Applicability. This standard defines test and validation requirements for single-core cables. It also applies to individual cores in multi-core cables. 1.3 Remarks. Single-core cables are classified by nominal voltage of the system where the cables are used, by the wall dimension of the cable insulation, and by the operating temperature. 1.3.1 Nominal System Voltage Classes. 



60 V cables intended for use in road vehicle applications where the nominal system voltage is < 60 V DC or 25 V AC. 600 V cables intended for use in road vehicle applications where the nominal system voltage is in the range of (60 VDC or 25 V AC) to (600 V DC or 600 V AC) inclusive.

Note: Note: For 600 V applications, the cable shall meet the 600 V performance requirements of ISO 6722-1, regardless wall thickness construction. V AC is Volt Alternating Current and V DC is Volt Direct Current 1.3.2 Temperature Classes. Eight Classes. Eight (8) cable classes have been defined in Table 1 to respond to the various temperatures encountered on vehicles. Table 1: Temperature Class Rating ISO Temperature Class

Note 1: For Structure A and B, cross-sections consisting of more than 80 strands, a minor deviation in number of strands (± 3%) is acceptable, provided that the electrical resistance and the maximum strand diameter still are met. Other stranding configurations may be acceptable, if approved by GM Engineering. Note 2: For sizes 0.13 mm2 to 2.0 mm2, all new programs to use Type A construction. For sizes 2.5 mm2 or larger, either Type A or Type B can be used. Type “C” is for “High Flex” applications, where high flexibility and flexlife durability is desired.

4.3.6 Conductor Cross-Sectional Area (CSA). This test is intended to verify that the cable conductor CSA fulfills the specified requirements. Method 1. In case of dispute, Method 2 (weight method) will be the referee method to determine the CSA. By using the resistance value R L,20 according to ISO 6722-1, the CSA is calculated using the following formula.

Where: A R L,20 Κ

is the cross-sectional area in mm 2 is the conductor resistance (Ω) at 20 °C is the conductivity of the used conductor material in Sm/mm 2 



f b

for copper, use a conductivity of 58.0 Sm/mm 2 for other copper alloys with different conductivity, values can be used based on the agreement between the customer and the supplier

is the bunching loss, depends on strand construction

Method 2. 1 m ± 5 mm of the cable under test is carefully stripped of all insulation. The conductor is weighed with a scale capable of measurement to 1 mg accuracy. From the result, the CSA is calculated using the following formula.

Where: A is the cross-sectional area in mm 2 m is the conductor mass in g γ is the density of the used conductor material in g/mm 3 Note: For copper, use a density of 8.89 g/mm 3 A different density may be used for other copper alloys Requirements. The values shall be within the limits according to Table 6.
