Technical Information
ACF (Altitude Correction Factor)
According to IEEE 1312 – 1999 standard, given the deterioration of the insulation quality in higher altitudes (for each 1000 m above sea level, the insulation quality decreases by around 10%), the altitude correction factor must be calculated and considered according to the following diagram.
For instance, in a 2000-m altitude, the altitude correction factor is 0.79 according to this diagram. Therefore, if the used voltage is 36kV, the selected cable termination is as follows by applying the correction factor.
Therefore, the selected cable termination in a 2000-m altitude and 19/33/36 kV voltage must be 26/45/52 kV cable termination.
Types of Cable Shields
The following table specifies the cable type in the products supplied by this company:
| Code | Description | Code | Description |
| 1 | With wired shield graphite | 1 | Non-armored and without lead |
| 2 | Without wired shield graphite | 2 | Non-armored with single lead |
| 3 | With taped shield graphite | 3 | Non-armored with three leads |
| 4 | Without taped shield graphite | 4 | Armored without lead |
| 5 | With graphite and no shied | 5 | Armored with single lead |
| 6 | Without graphite and shield | 6 | Armored with three leads |
| For instance: 53 shows use of a certain cable termination or joint for armored single lead cable and cable with taped shield graphite. | |||
