Application:
HV test shielding room  (faraday cage) are Widely used in power cable, transformer, transformer switch, transformer substation and other High voltage levels of partial discharge test or impulse test.
For HV testing shielding room, as a HV test place, it should has good electromagnetic
shielding condition. And its electromagnetic compatibility always is of great importance.
Firstly, it should restrict electromagnetic wave into inside shielding room caused by
discharge when making HV test to weakening interfere to outside, especially on
electronic and communication system. Secondly, it should prevent outer
electromagnetic wave intruding into shielding room to cause measurement error of
partial discharge and wireless. Thirdly, it should reduces open circuit voltage and
closed current to restrain common-mode interference so that to avoid equipment
damage and to improve accuracy of impulse measurement.
For  GIS HV test shielding room, design area is 500 m2ï¼?Length 25mã??Width 20m).
From provided information , we find that steel structure have been completed
already with one set of 20T crane indoor, crane supporting corbel also completed, the
height is 17.9m from ground to upper part of corbel. Main door height 13m,width 10m,
locates at downward of the west side, the door open direction towards to north .
According to ILJIN drawing, three side of structure column has already, but western
structure column still missing yet. however, as the main door will be located in this side,
the western side also should have steel structure , and this structure position still should
be unified considered with main door installation. We will be able to submit suggested
design diagram with position & size of this structure column for reference. in order to
save  construction cost, the construction engineering will be carried out by ILJIN
team.

Resistance Test Instrument Supplier
ZY9733 and ZY9734 digital desk type low current resistance measuring meters are suitable for units concerned to measure the DC resistance of various components and parts with certain limitations on current, such as platinum resistor, coppery thermal resistor, PTC ceramics, thermistor and various wire rods, etc.
1. Key features
1.1 It adopts a large green LED to display measured value, which is striking and clear. It also adopts the four-terminal resistance measurement method to eliminate the impact of conductor resistance, and the measurement accuracy is high.
1.2 There are a variety of specifications, and each specification has four scales to meet the measurement requirements of different users.
1.3 The test current is lower than similar equipment, which effectively prevents the impact of components and parts on resistance.
1.4 ZY9734 type has a RS-232 serial data output interface to facilitate the connection to computer.
1.5 It adopts a novel plastic shell and can changes the inclined angle between the device and table by adjusting the handle position, so as to determine the suitable panel observation angle. It has a well-designed appearance and is easy to use.

2. Main technical indicators
Temperature: Reference conditions: 20±5; nominal condition: 5~35
Relative humidity: Reference conditions: 40~60%; nominal condition: 25%~75%
Power source: AC 220V±10%, 50Hz, power consumption: About 5VA.

Scratch Grinding Tester
Automobile line inspection equipment
Wire and Cable Detection Equipment
It is applicable for assessing the scratch-resistant performance of automobile wire insulation with external forces in line with the requirements of GB/T12528-2008.

Main parameters:
1. The scratch grinding device exercises in two directions along wire axes with a stroke above 10mm
2. Exercise frequency: 50~60 cycles/min
3. Minimum distance between test points and test point and test sample end: >10mm; rotation angle of test sample: 90°
4. Length of test sample: Test sample which is about 750mm is firmly fixed to a steel anvil
5. Weight: 400, 700, 1000g (weights applied to scratching needle)
6. Function: The device will stop when the scratching needle grinds through insulation and comes into contact with conductor
