1. For the mechanical characteristics test of 110-500kV circuit breaker with closing resistor.
2. Measure 500KV and below SF6 switch, GIS combination electric appliance, vacuum switch, oil switch mechanical characteristic test 3. Equipped with straight line and rotation sensor, it is equipped with universal sensor to make speed measurement more convenient.
4. It can measure the current value of the winding and closing of the coil and draw the current waveform.
5, can automatically complete the low-voltage circuit breaker experiment, measure the circuit breaker operating voltage value high-voltage switch dynamic characteristics tester has the following characteristics:
1, performance 1) time: 12 fractures inherent points, closing time, with the same period, between the same period.
2) Closing resistance: Pre-casting time of 6 fracture closing resistors, pre-cast waveform and resistance.
3) Recloser: Coupon, Split-combine, Split-combine-minute process time of each break: One minute time, one closing time, two closing time, gold short time, no current time value.
4) Bounce: Bounce bounce time, number of bounces, bounce process, bounce waveform of each break, and the amplitude of bounce and rebound of each break.
5) Speed: just divided, rigid joint speed, maximum speed, time-stroke characteristic curve.
6) Stroke: total stroke, open distance, over travel, overshoot stroke, rebound amplitude.
7) Current: Points, closing current values, current waveforms of the split and close coils.
Action voltage: DC30～250V/20A digital adjustable breaker power supply is provided in the machine to automatically complete the low-voltage action test of the circuit breaker and measure the operating voltage value of the circuit breaker.
2, high-voltage switch characteristics tester features:
Applicable to all types of domestic and foreign production of SF6 switches, GIS combination appliances, vacuum switches, oil switch mechanical properties test.
The superior anti-interference ability can also be easily tested and accurately measured under the condition that the bypass bus of the 500KV substation is live.
Universal speed sensor, linear linear sensor, rotary sensor, installation is very convenient and simple.
The switching action is performed once and all the data of the switch mechanical characteristic test and the corresponding waveform diagram are obtained.
The host computer can store the field test data, the real-time clock inside the machine, and it is easy to archive the test date and time.
our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general forming process as the below sketches 
Technical Delivery Condition
1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in diameter.
2,Enquiry/order required information
We can give our clients once they gave us the below information
But if clients tolerance is higher than below Hokkai standards, it shall be provided to Hokkai prior to offer or ordering.
