Company Profile
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.
