Product Introduction

Product features

■ High quality high temperature resistant metallised polypropylene film is used as the medium, with low loss, low heat generation, low temperature rise and strong self-healing ability, resulting in a longer operating life.
■ Automatic vacuum drying technology is used to remove air and water molecules from the core pack, resulting in more stable performance and better electrical performance, minimising capacitor losses and maintaining excellent and stable electrical performance even in long-term operation.
■ The combined structure is only 1/2 the size of a normal, cylindrical product and is easy to install.
■ Light weight, semi-solid filled media, fusing below 70°C, effective explosion-proof construction, safe and reliable.
■ The product is sealed as a whole, and the internal over-voltage automatic cut-off safety protection device and temperature sensing components are adopted, which is of international advanced level in terms of safety performance, and the capacitor only shows open circuit or temperature sensing disconnection status when it fails.
■ Built-in discharge resistor, voltage drops below 75V within 3 minutes after the power supply is cut off (special requirements specified separately).
■ Synchronous design and manufacturing process with European and American products, can take a common complement, sub-complementary mixed complement structure, the use of reasonable, stable and reliable electrical performance of the product, and easy to install, simple, (with the installation foot).

Note .

Please specify any other special dimensions and performance parameters when ordering.

Typical applications

■　Widely used in 50Hz or 60Hz power systems to compensate for reactive power (can take common or mixed complementary structure), improve voltage quality and increase transformer efficiency.
