The primary distinction between MV-90 and MV-105 cables lies in their maximum operating temperature ratings. MV-90 cables are rated for continuous operation at temperatures up to 90°C, while MV-105 cables are designed for higher temperatures, supporting continuous operation up to 105°C. This difference allows MV-105 cables to handle higher thermal loads and makes them suitable for environments with elevated temperatures.
Both MV-90 and MV-105 cables commonly use insulation materials such as Cross-Linked Polyethylene (XLPE) and Ethylene Propylene Rubber (EPR). However, the insulation in MV-105 cables is formulated to withstand higher temperatures, providing enhanced thermal stability and performance in demanding conditions.
Due to their higher temperature rating, MV-105 cables can carry more current than MV-90 cables of the same size. For example, a 500 kcmil copper conductor rated for 15 kV may have an ampacity of approximately 480 amps for MV-90 and 535 amps for MV-105. This increased ampacity allows for more efficient power transmission in applications requiring higher current loads.
MV-90 cables are typically used in standard power distribution systems, suitable for indoor and outdoor installations where temperatures do not exceed 90°C. In contrast, MV-105 cables are preferred in more demanding environments, such as industrial facilities, power plants, and areas with higher ambient temperatures, where their higher temperature rating and ampacity are advantageous.
MV-105 cables generally have a higher cost compared to MV-90 cables, attributed to their enhanced insulation materials and higher performance specifications. When selecting between the two, it's essential to balance the application's thermal requirements with budget constraints to determine the most cost-effective solution.
In summary, the choice between MV-90 and MV-105 cables depends on the specific requirements of the electrical system, particularly concerning operating temperatures and current-carrying capacity. MV-90 cables are suitable for standard applications with moderate thermal demands, while MV-105 cables are designed for higher temperature environments and applications requiring greater ampacity.
