We do also an official distributor of RITZ instrument transformer, please browse to see from the menu..

 

There are many other brand products that we provide i.e. MV Capacitor Banks, Power and control cable, Battery Charger, Electronic components (Assure every pieces is working), AC/DC converter module, Din Rail Enclosure etc.

We also do all kinds of panel boards made in Thailand. They are Relay Board (swingrack type), marshalling board, DC distribution board, Console Rack, Junction Box, RTU board.

With our global network, we do seek for the hard to find spare parts i.e. Power Generator/Turbine spare parts, for our customers as well.

Medium Voltage Switchgear IEC standard

We provide IEC (International Electrotechnical Commission, European standard)  type tested medium voltage switchgear from 2 manufacturers. One is GE Secogear from Shanghai, China and the other is Siemens from either Jarkata, Indonesia or from Thailand. There can be air insulated switchgear (AIS) using air as insulation medium for all the busbars and MV components (like CTs, PTs, support insulator, earthing switch) or can be gas insulated switchgear (GIS) using SF6 gas as insulation for all busbars and MV components. There is also the option for better environment we culd use 50% SF6 + 50% N2. This latter can also devided as per the light duty (we call Ring Main Unit) and heavy duty (we call Gas Insulated switchgear GIS). The circuit breaker is vacuum type circuit breaker that use vacuum as a switching medium.

The switchgear can be equipped with any protection relays from any maker, like GE Multilin, Siemens Siprotec, Alstom and etc. The switchgear can be equiped with arc protection devices like VAMP or ABB. The Substation control system can also implement in the switchgear using intelligent relay protection set. The switchgear can also be equiped with special windows for Thermal image scanner to check the fit busbar connections.

We will do all the design work i.e. single line diagram, foundation layout, panel layout, schematic diagram, wiring terminal list. we can also do relay setting coordination study providing that the network data received from the customer.

After delivery, we could provide installation and commissioning for them. The standard warranty is 1 year with the option to extend it to 3 years.

We have experiences working with the sophisticated consultant like Foster Wheeler, Technip and etc. the documentation required is not concern us.

The rating of the IEC standard switchgear are as follows;

Technical Rating AIS GIS
Rated Voltage 3.3-45kV 3.3-45kV
Rated Current 630-4000A 200-4000A
Rated short circuit current 25kA-50kA, 1or3sec. 16kA-40kA, 1or3 sec.
Internal Arc rating 25kA,31.5kA, 40kA 1 sec 16kA, 25kA, 31.5kA, 40kA 1sec

The rating that is rarely find from the market is 24kV and 31.5kA can be quoted by us.

 We could also provide medium voltage switchegear with marine certificate.

For Ring Main unit we could provide 630A 36kV rating.

 

 The gas insulated switchgear can be IEC or GB standard

PCB Electronics Assembly

We do PCB Electronics Assembly from prototype 5-6 sets up to mass production. We could also provide the chassis, boxes, cases made from aluminium, steel or plastic as per the requirement. The chassis, boxes and cases are prioritized to be made in Thailand. The complete electronics module with wiring fixed neatly inside its enclosure.

With the design and PCB files from the customer, we procure the required components (resistors, capacitors, LED, ICs, push boton, connectors and etc..) from the reliable source like Digikey, Element14, Mouser, RScomponent and Electronic Soruce. We could also sourcing the hard to find parts. All the components are re-checked again by us. We provide good quality PCB of upto 32 layers. The components are planned and solder into the PCB upto by SMD soldering machine. They are done according to Acceptability of Electronic Assemblies (IPC-A-610). We do both ROHS products and non-ROHS products. all of the assembly are done by our sub contracting ISO9000 factories in Thailand.

 

 

We do CPU, Microcontroller programming into the module and run the test. We could do tests that are required by the customer. The self test programming shall be from the customer..The non-pass units are to be re-checked according to the circuit diagram to find the problems parts or soldering putty. then the replacement or adjusting of the parts are to be done.

MV swichgear for Induction furnace of Siam Kubota project.

 

 

The switchgear is local made in Thailand using Siemens 3AH circuit breaker and SEG protective relays. The switchgear feeds power to 4 winding transformers to get rectified through the low voltage control system. 

There are 2 outgoing feeders to the rectify transformers. The incoming feed is connected directly to busbar of the switchgear.


See the mimic diagrams in the panel photo.

 

We do manufacturing of the switchgear, delivery to site, install and commission them successfully.
