Single Core 1.9/3.3kV Copper Medium Voltage Cable

Single core copper medium voltage cable, the nominal voltage rating is 1.9/3.3 (3.6) kV, which means it is suitable for applications requiring medium-voltage power transmission. Such a voltage rating is often found in industrial and utility distribution systems where reliable and consistent power supply is crucial. This level of voltage is ideal for powering equipment in various industries, including mining, manufacturing, and energy generation.

Min. installation temperature: 0°C

Operating temperature: -25°C to +90°C

Emergency operating temperature: 105°C

Max. Short Circuit Temperature: 250°C

Application

1.9/3.3kV copper medium voltage cable is suitable for infrastructure power distribution, such as power transmission in factories and manufacturing facilities, especially in the medium voltage range, to ensure efficient and safe power supply.

FAQ

Q: Is 3.3 kV high voltage?

A: No, 3.3 kV is not considered high voltage. It falls under the category of medium voltage.

Voltage classification is typically divided as follows:
• Low Voltage (LV): Up to 1 kV (e.g., household wiring at 230V or 400V)
• Medium Voltage (MV): 1 kV to 36 kV (e.g., 3.3 kV, 11 kV, 33 kV distribution systems)
• High Voltage (HV): 36 kV to 230 kV (e.g., long-distance transmission lines)
• Extra High Voltage (EHV): Above 230 kV

Q: What is a 1.9 /3.3 kV cable?

A: 1.9/3.3 kV cable is a type of medium voltage (MV) electrical cable used to transmit electricity in systems with a nominal voltage rating of 1.9 kV between conductors and ground, and 3.3 kV between conductors.

Q: How do I choose a power cable size?

A:Choosing the right power cord size requires considering many factors, such as current (amperes), voltage level, distance, temperature rating of the cable, installation environment and many other factors. You can contact us and we will provide you with a suitable solution.
