China Transmission and Distribution Project Contractor and Supplier Product data

Transmission, distribtution and substation are our starting company business for more than 20 years. We have gathered the strength from all aspect from China in power transmission industry.

Within these turnkey or EPC transmission, distribution, substation projects, we have provided, installed, commissioned the whole system and every equipment and electric products:

XLPE power cable, copper conductor cable, fiberglass cable. Amoured cable, underground or overhead and even submarine undersea power cable of high voltage such as 132kv to 600kv.

Transformer, from 1000kva to 400mva, high voltage to 600kv.

Porcelain and Sillicon rubber insulator;

breaker, SF6, switchgear, lightning, earthing equipment.

Capactitor, or power tower, lattic tower.

1�?/SPAN>transformer

1.1 on the single line drawing, the capacity and cooling method is 25mva and ONAN/ONAF, but in documents Teknik __artname 1 and Teknik __artname 2 we found that the capacity is 15mva, and in Teknik __artname 1, 2.6 the cooling way is ONAN/ONAF /ODA. So please clarify.

1.2, the connection in Teknik __artname 1 is YNd11, but in Teknik __artname 2, it is YNd1, please clarify. In the tendering documents, it is saying There shall be three outgoing 11kV feeders from 132/11kV, but in the single line drawing, there are 6 outgoing 11kv.

2�?/SPAN>in the single line drawing, there is not showing of any earthing switch on the side of isolation switch lines, but they are required in the tendering documents.

3�?/SPAN>To the requirements of measuring and protection, there should be 132kv potential transformers, but in tendering documents, it says: 3.4 Voltage Transformers(Not Applicable to this Bid), which is also not shown in the single lines.

4�?/SPAN>in the Teknik __artname 2, 4.0 11kV Switchgear Panels format item 27, b, CT ratio is 1600/800/5A�?/SPAN>but in single lines the ratio is 1600/5A, please clarify.

5�?/SPAN>in Teknik __artname 2,4.0 11kV Switchgear Panels�?format item 28, b, CT capacity is 5VA�?/SPAN>but in single line it is 15VA�?/SPAN>please clarify.

6�?/SPAN>“Teknik __artname 2, 8.0 11kV Neutral Point Earthing Resistor�?format 15, b, the CT ratio is 300-150/5/5A , but in single line it is 300-150/5A, please clarify.
