Multi-pole arc type slide wire performance and main features
The requirements of the multi-pole tubular arc-shaped sliding contact line are as follows: 1. Tubular multi-polar arc-shaped sliding contact line, and the arc radius of the guide rail must be greater than or equal to 1.5 meters to produce;
2. The workshop must be dry, otherwise it will affect the performance of the trolley line.
3, multi-pole curved trolley current can be divided into: 50A, 80A, 120A, 140A and other national standard current;
4. Conventionally, the length of single pole of multi-polar curved trolley line is 2.5 meters, which can also be intercepted according to customer requirements, but the interception length is generally less than 3 meters to facilitate the installation of the transportation and trolley line;
The main features of the multi-pole arc-shaped trolley line are as follows:
1. Arc-shaped trolley wire is simple in structure, easy to install, easy to maintain and maintain;
2. The arc-shaped trolley line can be used in places with radian and the application is more flexible;
3. The arc-shaped trolley line is composed of copper conductors and can achieve energy saving of about 15% to 20%, which saves material and installation costs.
4. The trolley wire is composed of a polymer PVC shell and is embedded with a plurality of copper sheets. It has a long service life and adapts to the general environment.
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Natural Gas Mass Flow Meter, Natural Gas Mass Flowmeter, Natural Gas Coriolis Meter, Natural Gas Coriolis Mass Flow Meter, ATEX, IECEx & CE approved.
First, Sealand meter is certified by Zhejiang Institute of Metrology. To get such certificate, Sealand has to send all models to Zhejiang Institute of Metrology and all models are tested in their calibration lab. The lab is an ISO/IEC 17025:2005 standard lab approved by CNAS (China National Accreditation Service for Conformity Assessment). CNAS is a member of ILAC (International Laboratory Accreditation Cooperation).
Second, Sealand has its own calibration lab, equipped with METTLER TOLEDO scales with accuracy 0.014% and the device extended uncertainty is 0.05%. The lab is also approved by Zhejiang Institute of Metrology. This certificate will stay valid only for one year, Zhejiang Institute of Metrology will send their professor to Sealand every year to check and make sure that the lab is qualified still and then issue new certificate. During the production, each meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
Finally, Sealand also gets ISO, CE, SIL, ATEX & IECEx. Sealand is the only Chinese brand who gets ATEX & IECEx and it is from TUV SUD ( the most authoritative institute for ATEX).
