Jinma 440V to 380V Step-down Isolation Transformer is specially customized for Cuba 440V power grid working conditions. It can accurately stabilize and output 380V rated voltage, and completely solve the problems of 380V industrial equipment overvoltage damage, shutdown, process misalignment, etc.
The equipment adopts high-permeability silicon steel core and high-purity oxygen-free copper winding, which is processed by numerical control precision winding and vacuum dipping curing process, with accurate magnetic flux control and stable performance;
Equipped with intelligent voltage regulator module, it can quickly respond to power grid fluctuation in 0.3 seconds with constant output voltage. The power covers 15kVA-150kVA and is suitable for all kinds of industrial production line equipment.

380V equipment has been operated in 440V power grid for a long time, the core components continue to overpressure load, the insulation aging is accelerated, the failure is high, the problems in the mass production stage are particularly concentrated, the main losses include:
Ordinary general-purpose pressure relief equipment can not adapt to the continuous and stable production needs of the Cuban industrial scene, there are two core defects, it is difficult to meet the use of mass production conditions:
The fluctuation of the output voltage of the equipment exceeds ± 3%, and the voltage stability is poor, which can easily lead to the deviation of the production process, resulting in frequent equipment failures and unable to guarantee the continuous and stable operation of the production line.
Only a single fixed power equipment matching is supported. Once the production line is upgraded, modified or expanded, the equipment needs to be purchased again, resulting in repeated investment and greatly increasing the long-term operation and maintenance and production costs of the enterprise.
In order to ensure stable equipment adaptation and smooth landing and production, the following standards can be used for selection, installation and after-sales matching:
Reasonable power redundancy shall be reserved during selection, and the model shall be comprehensively matched with the rated power, load type, starting mode and field working conditions of the equipment to effectively avoid overload risk and ensure long-term stable operation.
Equipment adaptation multi-scene installation form, no need to modify the original plant, manufacturers can provide the whole remote installation, wiring and commissioning guidance, high landing efficiency.
Provide one-to-one customized selection scheme, with 24-hour after-sales response service. At the same time, it can assist customers to check the export compliance requirements such as local import certification and customs clearance rules in advance to avoid the risk of going to sea.
Industry-wide, all 380V three-phase industrial equipment adapted to Cuba 440V power grid can be used.
The installation method is flexible, without large-scale transformation, the whole process of remote guidance, landing efficient.
Equipment efficiency of more than 97%, very low loss, compared to downtime maintenance, replacement loss, can significantly reduce the overall cost.
It is recommended to verify the local import certification, customs clearance rules and warranty terms in advance to ensure smooth landing and production.
