Concentric Conductor Electric Cable with PVC Insulation and Sheath

Concentric Conductor Power Cable

■ Application

The product is suitable for electric power transmission and

distribution network circuit with rated voltage 0.6/1kV and including.

■ Product Characteristic

1. It has lower and uniform positive (inverted) sequence and zero sequence impedance, which can

improve the quality of electricity supplied.

2. Comparing with the fourth core of common 4-core cable, the reactance value of concentric

conductor is much lower than the working condition of zero sequence, which can improve

sensitive action of short-circuit auto-protection device and can ensure cable and relative equipment

for safe operation.

3. It has strong properties of anti-electromagnetic interference and anti-thunder strike.

4. Five-core cable is suitable for power supply of TN-S and TN-C-X system.

■ Type designation and specification

■ Schematic figuration of structure

1. Conductor

2. Insulation

3. Filler

4. Wrapped tape

5. Inner separator

6. Outer conductor

7. Wrapped tape

8. Outer sheath

■ Technical parameter

1. D.C. resistance of conductor is referenced to the cable with PVC insulation and sheath.

2. The finished cable shall be subjected to A.C. voltage of 50Hz 3500V 5min and result should not be breakdown.

As far as single core is concerned, it should make voltage resistant test after immersing water.

3. DC resistance value at 20℃.

■ Delivery length

Delivery length of single piece is not less than 100m, short section with length not less than 20m, is permitted, but the quantity shall not exceed in ±10% of total quantity.

Any length of cable can be delivered as per mutual agreement.

The tolerance of length shall not exceed in ±0.5%.

Hebei New Baofeng Wire & Cable Co., Ltd. owns fixed capital of RMB 1.6 billion with 1100 staffs (among whom 86 are senior engineers and technicians, 230 are engineers and technicians). The Group Co. consists of 18 departments, 11 branches, 32 representative offices with its sales networks covering 50 big and medium cities of China.

Equipped with high quality technical expertise, latest manufacturing and inspection equipments as well as Research & Development activities , Hebei New Baofeng Wire & Cable Co., Ltd. has become not only a leading cable manufacturer but also a Group company with reputation for delivering quality cables at competitive prices and within the committed delivery schedules in the international market.

HNBF has the most present advanced cable auto-producing lines and cable testing equipment in the world: the highest 750kV extra high voltage vertical producing line in the world, 10-110kV dry CDCC XLPE cable line, 1-10kV the one-step-method four –layer co-extrusion cross-linkage cable producing line, 10-110kV partial discharge testing equipment imported from Siemens, Germany, and 1000kV thunder and lightning surge testing equipment imported from Haefely Co., Switzerland.

As a technology breakthrough, we have developed 630-2500mm²sectional area sub-marine cable, which is the highest level. The one-step-method four-layer co-extrusion Silone cross-linked cable, High Voltage and Extra High Voltage cables 66kV to 500kV，35kV and below XLPE insulated, non-smoke and non-halogen A series rire-retardant power cable, 35kV and below XLPE cable for semi-conduct electric screening, visual spiral Aluminum Cored XLPE power cables, XLPE insulated, rat-proof shielded, low-smoke and low-halogen A serial fire-retardant and ultraviolet-proof power cable, XLPE insulated termite-proof power cable, as well as 3kV XLPE insulated water-proof and rat-proof power cable, A serial cross-linkage fire-fighting cable, and other new cable products for special-purpose Cable Accessoriesfor 66kV-500kV cables. We have more than 50 items over which we own the intellectual property rights / patent rights.

In 2001, our predecessors Baofeng Cable Co. Ltd. developed the first 500kV extra high voltage cross-linkage cable in China with its Partial Discharge less than 0.8pc. In short, we can say that we have given a new control index data for the IEC standard, we can also say that China actually was one of the earliest producers of 500KV High Voltage Cable other than Germany and Japan.

In recent years, our products are exported not only to countries and regions of Europe, Asia, Africa, as well as USA, New Zealand.
