between two flexible insulated busbars: ≥30kV.

Main features of flexible insulated busbars: Easy assembly: it could be easily bended and fixed with hands or easy

tools.

Possibility of reducing sizes of the equipment:

Due to favorable thermal radiation properties, the flexible insulated busbars can handle heavier current loads than solid busbars of the same cross-section.

Due to good insulating performance of the PVC, it could be possible to reduce the distances between different flexible insulated busbars and between the flexible insulated busbars and earth.

The bending-radius could be smaller than that of normal cable or solid copper bars, so that the connections could be more simple and short.

Lower temperature rise on the flexible insulated busbars than on normal copper bars.

High flexibility: no problem with vibrations or thermal expansions.

Application of flexible insulated busbars: The flexibility of the bars makes it possible to install into difficult equipment or small places very easily. They can be particularly well used as connectors in switchgears and between transformers, switching devices and prefabricated power networks.

Dimensions and ampacity Standard length: 2m or 3m (for 1-layer busbar, 25m in roll is possible).

Cross-section: up to 1200mmm2.

Ampacity: values in the table are only for reference because the actual ampacity is related to the application conditions.

We can produce pre-formed flexible insulated busbars according to

Guidance for selecting the correct dimensions The ampacities are related to the cross-sections and operating ambient temperature, as shown in above table. Therefore, three factors should be considered for deciding the dimensions:

Ampacity

Allowed temperature-rise on the flexibars

Width of the flexibars

The temperature-rise △T can be calculated with formula:

△T=Tr – Ta

Ta: ambient temperature

Tr: temperature of bars at rated current (pay attention: for general electrical apparatus, Tr should be ＜105℃).


Page: 13 / 22

Example (just for reference):

If operating ambient temperature is 40℃, and you need ampacity 510A with bar width ＜ 40mm, you could get allowed highest temperature-rise 65K (105℃-40℃=65K), so you could decide dimension 32×1×4. With this bar, the highest temperature-rise will be 50K with current 520A.

4. Liquid-cooled Heat Sinks

We produce liquid-cooled heat sinks sealed with friction stir welding (FSW) technology.

Friction Stir Welding (FSW) is a solid-state joining process in which the welding is done with frictional heat generated between the welding tool shoulder / pin and the materials of the work pieces. The heat causes the stirred materials to soften without reaching the melting point so that a solid-state joining could be achieved. The joint has a monolithic structure with mechanical properties similar to the parent materials of welded parts.

The FRICTION STIR WELDING TECHNOLOG is with outstanding advantages:

Excellent weld quality and repeatability

High reliable sealing

With high strength similar to the parent materials of welded part

No pores

No flaws

No residual stress

No deformation

No smoke dust, no splash, very low noise in production

The heat sinks can be made with copper or aluminum and coated according to customer specification.

Our design is based on the ICEPAK - the most advanced thermal design software for electronic equipment, and the validity of the thermal and flow performance is verified by simulation and testing.

The welding quality is checked with X-ray tester and the leakage test is made according to customers’ requirements, for example 6~12 bar applied for 10-24 hours with pass criterion of pressure loss at the end of test < 0.2 bars.

5. Mechanical & Electrical Components 5.1 Shock absorbers (oil dampers)

The shock absorbers are basically oil pumps: a piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the load travels up and down, the hydraulic fluid is forced through tiny orifices inside the piston. However, these orifices let only a small amount of fluid through the piston. This slows down the piston, which in turn slows down the load movement and absorbs the shocks. The amount of resistance a shock absorber develops depends on the speed of the load and the number and size of the orifices in the piston.

We produce different type adjustable and non-adjustable shock absorbers. High quality components and strict process control is designed to assure the high quality of the shock absorbers: no oil leakage, reliable functions, long service life.

5.2 Draw-out units Draw-out unit is important operating mechanisms used in switchgears for realizing interlocks of door, shutter, VCB and earthing switch. High manufacturing precision is required for the product to achieve reliable interlocks. We can manufacture different types of draw-out units.

5.3 Load break switch (arc-strangler switchblade)

The load break switch is a switchblade with integral arc-strangler load breaking device for hinge-style mounting:

This product includes a stationary core and a spring-loaded sliding sleeve which could quickly cut off the arc produced between the mounting contact and blade during load breaking operation.
