Product Introduction：This product is suitable for fixed installation on AC 50HZ, rated voltage 35V and below power transmission and distribution lines for the purpose of transmitting electrical energy.
This product is suitable for fixed installation on AC 50HZ, rated voltage 35V and below power transmission and distribution lines for the purpose of transmitting electrical energy. Compared with PVC insulated power cables, cross-linked cable products not only have excellent electrical and mechanical properties, heat and aging resistance, environmental stress resistance, and chemical corrosion resistance capabilities; Moreover, it has the characteristics of simple structure, light weight, not limited by installation drop, and high long-term working temperature (90 ℃).
1、 Production execution standards
GB/T12706.1-2008-GB/T12706.3-2008 "Extruded Insulated Power Cables with Rated Voltage from 1KV (Um=1.2KV) to 35KV (Um=40.5kV)" can also be produced according to user needs using the International Electrotechnical Commission IEC60502-2004 standard.
2、 Usage characteristics
The allowable long-term operating temperature for cable conductors is 90 ℃.
During a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor shall not exceed 250 ℃.
3. The ambient temperature during cable laying shall not be lower than 0 ℃.
4. Minimum bending radius of cables: For three core cables, it shall not be less than 15 times the outer diameter of the cable, and for single core cables, it shall not be less than 20 times the outer diameter of the cable.
5. The rated power frequency voltage U0/U of the cable is 0.6/1KV-26/35KV
U0: The rated power frequency voltage between the conductor used in cable design and the ground or metal shield, referred to as the phase voltage
U: The rated power frequency voltage between conductors used in cable design is called line voltage;
Um: The maximum value of the "highest system voltage" that the equipment can withstand.
3、 Cable model name and applicable occasions
