• Specific property for usage of 110KV~220KV XLPE high-voltage cable

1. Cable’s conductor highest working temperature is allowed up to 90℃, and overload when meet an emergency is 130℃ ,When short circuit (in ≤5 seconds) the highest temperature is 250℃
2. When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.
3. The minimum bending diameter:

Note: In form, D₀ is a real test value to cable’s outer diameter.

1. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent section) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4.
2. Allowed biggest lateral-press P, when cable is being bent

The single core cable is required P≤500kg/m.

P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.

1. Cable laying is not being restricted by drop.

• The structure parameter and functions table to 110KV, 220KV XLPE high-voltage cable products

1. Rated voltage 64/110KV XLPE copper core and PE insulated wrinkled aluminum wrapper waterproof layer PE(or PVC) sheathed power cable.

Note: Current carrier capacity is made up by laying in soil abreast. The axial distances between cables are 200mm. Soil temperature is 25℃. The working temperature of cable is 90℃. The coefficient of soil heat-resistance is 1.2km/W.

1. Rated voltage 127/220KV XLPE copper core and PE insulated wrinkled aluminum wrapper waterproof layer PVC (or PE) sheathed power cable.

Note: Current carrier capacity is made up by laying in soil abreast. The axial distance between cables are 200mm. Soil temperature is 25℃. The working temperature of cable is 90℃. The coefficient of soil heat-resistance is 1.2km/W.

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.
