Hunan Hualian Torch Porcelain insulator & Electrical
apparatus Co. Ltd, is Leading manufacturer of China porcelain
insulator industry and electrical industry.* with 66 years's
glorious history.* The permanent member of National Electrical
Porcelain Industry Association.* One of national top five
electrical porcelain manufacturers.* factory covers an area of
190,000 square meters, with building area of 92000 square
meters.The porcelain insulator are used
on substation & transmission Line. It helps to
support and hand wire, insulation wires against tower.Product
DisplayComposite Post InsulatorThis product is applicable to the
technical reform of city network, which can effectively use narrow
corridor area of city to boost power transmission, can reduce the
height of tower, save lots of financial and material resources.
Because of its high bending strength, it can prevent fracture
accidents which easily happen in porcelain cross arm insulator, and
it has good pollution resistance, porcelain cross arm can not be
replaced. Dimension&Property replaced.TypeCenter

electrical function. Product structure Our company
specially produces composite insulator for power transmission line,
the important structure is made of shed housing, epoxy fiberglass
core and metal end fittings. The surface of terminal end fittings
is covered with zinc coating(hot-dip galvanization) for corrosion
protection. Compared with same type ceramic and glass insulator,
silicone rubber insulator has the following advantages:(1)Small
volume, light weight(is 1/7~1/10 times than ceramic insulator in
the same voltage), sheds have good elasticity, not broken,
convenient transportation and installation, economy.(2)High
mechanical strength. FRP ROD has high tensile strength, which is
5-10 times than ceramic materials, for core is small cross section,
which makes the products small size, light weight, high tensile
strength, and easy to manufacture more than 300KN large tons
insulators.(3)High antifouling property, good aging resistance
performance, the sheds made of silicone rubber injection mold has
good hydrophobicity and migration, which makes insulator high anti
pollution flashover voltage and good electric corrosion
resistance.(4)Easy installation and maintenance, can greatly reduce
outage loss which cause due to maintenance and maintenance charges
which cause by manual labor intensity.(5)Simple production process,
short delivery time.PRODUCTS
