Operation character

Fire-resistant property

(1) According to national standards, fire-resistant wire and cable fire test method characteristic

test, according to GB12666.6

Class A, burn in fire with flame temperature 950°C, apply voltage of 750V between phase and

phase and between phase and outer sheath,it should be able to withstand for 90min without

breakdown.

Class B, bun in fire with flame temperature 750-800°C, apply voltage of 750V between phase

and phase and between phase and outer sheath,it should be able to withstand for 90min without

breakdown.

(2) According to the BS6378,flexible fireproof cable satisfies the following requirements:

Class A 650°C 3h

Class B 750°C 3h

Class C 950°C 3h

Class S 950°C 20min

Electrical characteristics

(1) Rated voltage: 0.6/1kV

(2) Rated working voltage: light load 500V, heavy load 750V;

(3) Rated current: single-core 25A-1,800A: multi-core 16A-500A;

(4) Insulation resistance: insulation resistance≥ 1000MΩkm. Cable length less than 100m,

then the insulation resistance≥ 10000MΩ;

(5) Power frequency withstand voltage: apply voltage of 2,000V and 2,500V between phase

and phase as well as phase and copper sheath of cables of 500V and 750V respectively,

they should be able to withstand for 15min without being broken down.

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.
