GB/T 12706.2-2008 Power cables with extruded insulation and their accessories for rated voltages from 1kV (Um=1.2kV) up to 35kV (Um=40.5kV) - Part 2: Cables for rated voltages from 6kV(Um=7.2kV) up to 30kV(Um=36kV)
Power cables with extruded insulation and their accessories for rated voltages from 1kV (Um=1.2kV) up to 35kV (Um=40.5kV) - Part 2: Cables for rated voltages from 6kV(Um=7.2kV) up to 30kV(Um=36kV)
This part of GB/T 12706 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation from 6kV up to 30kV for fixed installations such as distribution networks or industrial installations.
When determining applications, it is recommended that the possible risk of radial water ingress is considered. Cable with barriers claimed to prevent longitudinal water penetration and an associated test are included in this part.
Cables for special installation and service conditions are not included in this part, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area) nor for submarine use or shipboard application.
