Bending Radius
Permissible bending radius for single-core cable: 20 (d+D) ±5%
Permissible bending radius for multi-core cable: 15 (d+D) ±5%
D = Actual outer diameter of cable (mm)
d = Actual diameter of conductor (mm)
Laying Temperature
Pre-heating is mandatory if laying is carried out below 0℃.
Laying Height Difference
No restriction on vertical height difference for cable laying.
All Qiancheng 26/35kV XLPE Insulated Power Cables complete full-set tests before delivery. All lab test results meet stable standards, eliminating hidden risks of insulation breakdown and short-circuit fire during long-term operation.
Flame-retardant versions effectively restrain longitudinal flame spread. For halogen-free low-smoke types, light transmittance during combustion exceeds 75 % with no toxic and corrosive halide fumes. Multiple urban underground utility tunnel projects have passed fire-supervision acceptance in one go with this cable.
Armored structure resists crushing and scratch from external excavation force. Outer sheath adopts weather-resistant PVC/PE material. For outdoor open-air and direct-buried installation, it provides resistance against UV radiation and acid-alkali soil corrosion, reducing frequency of on-site inspection and maintenance.
New-energy sector: Main transmission cables inside 35 kV step-up substations for wind power and photovoltaic projects.
Municipal power grid: Networking of urban 35 kV substations and upgrading of old high-voltage lines.
Industrial plants: High-voltage dedicated power supply lines for large-scale metallurgy, chemical and mine bases.
Municipal infrastructure: Power distribution for confined spaces such as underground comprehensive utility tunnels, rail transit and large-scale hub industrial parks.
A: There is no specific limitation on vertical laying height difference for this cable. It can be considered for installations with significant elevation changes, including shafts, slopes and mountainous sites, provided the selected construction meets the project requirements.
A: The halogen-free low-smoke version produces less smoke during combustion and does not release corrosive halogen-containing fumes. Its optical visibility and low-smoke characteristics can be advantageous in enclosed areas such as underground utility tunnels where fire and smoke requirements are more demanding.
A: The armored construction provides additional mechanical protection against crushing, impact and damage during excavation. Depending on the selected sheath material, the cable can also provide resistance to UV exposure and acid-alkali conditions in soil, making it suitable for outdoor and direct-buried installations where these conditions are present.
A: Finished cables undergo the relevant electrical tests specified for the product and project requirements. Test items can include insulation and voltage withstand performance, helping verify the cable's electrical condition before shipment and installation.
A: Typical applications include main power transmission circuits within 35 kV step-up substations for wind and photovoltaic power projects. The cable can also be considered for urban substation networks, high-voltage line renovation and dedicated power-supply circuits for mining and chemical facilities.
A: Direct laying is not recommended when the ambient temperature is below 0℃. Where low-temperature installation is unavoidable, the cable should be preheated according to the applicable installation requirements to reduce the risk of cracking or mechanical damage to the insulation and sheath.
A: The cable can be used for power distribution in enclosed engineering environments such as underground utility tunnels, rail transit facilities and large industrial parks. The appropriate cable construction should be selected according to the project's fire-performance, installation and environmental requirements.
