Corrugated Board for switch motor transformer electrical

Corrugated Board,switch, motor, transformer, electrical,insulation material 

The corrugated board is used for common oil-gap insulation in small transformers. The advantage of it is easy assembly and improved the allocation of solid insulating materials in the oil duct. Comparing with the strips in the radial stays in the oil passages in the corrugated board, solid insulation distribution is very uniform, there is no electric field perpendicular to the plane.therefore, the strength of the oil passages can be increased by about 15% without loss of reliability.To use thermoforming process to produce corrugated board has the following advantages: high mechanical strength, excellent electrical properties, dimensional stability, precise dimension.

Laminated Board for switch motor transformer electrical

Laminated Board ,switch, motor, transformer, electrical,insulation material 

LAMINATED BOARD are produced by laminating and hot pressing of multi-layers of
high-quality transformer boards(H4) together with improved phenolic resin, casein glue
and Polyester adhesive. Comparing with Laminated wood, laminated boards have the
advantages of higher density, better mechanical strength, higher electrical strength and
lower compressibility and better insulation property strength, they are suitable to apply
in generators and electrical equipment as insulation parts which requirement for high
mechanical strength , they can also be used in transformer oil .The maximum

Insulation Components of Oil-immerg Transformer for switch motor transformer electrical

Insulation Components of
Oil-immerg Transformer,switch, motor, transformer, electrical,insulation material 

Main Property Standard Value

Insulating components are made of 100% Electrical-grade pulp through special
designed moulds and processing methods or professional machines, which can ensure
application in oil-immersed power transformers for good mechanical strength and
insulation property.

Both of electrical and mechanical properties of insulating components depend on raw
materials quality and manufacturing methods. Different manufacturing methods will
result in different performance on final products.According to the diversities of
producing methods and techniques, insulation components can be classified into
three main categories: (1) special-shape parts molded by hands, (2) Molded
components by pressing and framing on machinery, (3) mechanical kits/components.
Special-shape parts are more complicated on shape-designs, such as Lead exits;
Components pressed & moulded by machinery, like clamps, angle rings, are made by
molds without adding any adhesive and additive; Mechanical kits/components are
made through processing of laminated boards into different parts.

The quality of insulation components should be conformed with the following standards:

1、Requirements on appearance

The dimension should be in conformity with design drawings;
The inside and outside surfaces of moulded parts should be flat and free of
delamination, cracks, ruptures, convex-concave,polluted spots, bubbles and holes.
and its transverse section should be smooth and free of burrs and carbonization.
The surface of Mechanical kits/components must be smooth and free of defects like
convex-concave, bubbles, polluted spots, etc; and the glue or adhesive must be even
and free of bursting, bubble, degumming and delaminations. All processed sections
must be smooth, no convex-concave and cracks more than 0.2mm, no carbonization,
no color difference due to density and processing.
Color of components should be natural as raw material, but part of shades deviation
caused by repairing under 30square millemeter per area are allowed. Burled depth is not exceeding 30% of the thickness. No burling marks on components with thickness less than 2 mm.

2、Requirements on machining property
The components should be endurable to mechanical process, such as shearing, drilling
and milling . They should be free of cracks, ruptures and carbonizing discolor caused
by processing.

3、Requirements on binding/adhesive agent

During the production process, the binding/adhesive agent required must perform very
well in adhesiveness, thermal resistance, aging resistance and compatibility with
transformer oil meanwhile be free of pollution to transformer oil.

4、Physics and chemistry property of components should conform to the standard as follow:

L-Insulating Supports for switch motor transformer electrical

L-Insulating Supports ,switch, motor, transformer, electrical,insulation material 

L-shape clamping insulation part, usually called as angle rail, is an ideal clamping
insulation part for oil immersed transformers, which has the benefits of good insulation
performance, high mechanical strength and easy assembly. Especially when the rail is
used in large-scale transformers more than 110KV, its advantages of straightness
and shape stability are more obvious, for which we can hardly find substitutes, in
addition, it is more economical.

WELLELE.com madeLaminated Spacers and threaded standoffs made of thermosetting resins (phenolic, expoxy, silicone or melamine), convolutely wound under high pressure and heat with other appropriate materials, have proved themselves in a wide variety of contemporary applications. Their insulating properties, resistance to extreme temperatures, and light weight make them particularly desirable for use in electronic and electrical equipment. Resistance to compression, impact, vibration, corrosion, and moisture are further benefits noise reduction is another. The material is easy to saw, drill, tap, thread, machine, polish, and punch with ordinary tools.manufactures and stocks a wide variety of types and sizes for immediate shipment. We will also custom fabricate standoffs and spacers or modify stock items to meet your special requirements. competitive quote in china . more know of us look at web CHINAVFT.com ,ALLINSULATTING.com ,EM salefiber@yahoo.COM
