Dear Sirs.
Transformer bushing fixing is one of the significant areas where specialized
equipment should be used to provide:
- low losses to conductivity
- wide range of applicable cable types
- ease of application and accessibility
Some of the major faults which have an impact on damage of the transformer
come from inapropriate temperature of transformer bushings according to low quality
materials used on bushing clamps. It is essential to establish efficient connection
between transformer bushing and cables, using right methods. Competent fixing is also
crucial to power loss and is strictly connected with materials and manufacturing methods.
The most common ways to produce clamps are: casting and drop forging.
As castings are often still being affected with many faults, the more efficient and
reliable method is drop forging. It may be still more costly on production, it will pay back
when fitted on transformer. Our high quality clamps have been designed to meet the most
demandful needs and provide simple, functional connection between transformer and
output cables. High purity of materials and advanced production used in our products will
result in energy saving.
According to our research where our product TOGA1 2x240 sq.mm was exposed
to I=500A during 3h period at T=20 degrees Celsius, we received following readings:
- max voltage loss - ?U=5mV
- max opeerating temperature = 33 degrees Celsius
- resistance = 0,000014 Ohm
- dissipated power = 2,5W
We are proud to present to you products of high quality and exceptional
properties. We kindly invite you to browse our range of products in this catalogue.
