product description:
The series of low-voltage cable branch box is mainly used for rated
frequency 50 / 60Hz, rated voltage 380v / (660v) public power grid,
as power, lighting and distribution equipment, power distribution,
control for a variety of malicious environment, change Power
distribution stations, industrial and mining enterprises and urban
roads, garden residential quarters, high-rise buildings, airports
and other outdoor public places. Particularly suitable for
petrochemical and other corrosive gas plants and coastal islands
and other high-salt, fog places. SMC glass fiber reinforced
unsaturated polyester box, the use of new high-performance
materials processing, with ordinary materials do not have the
advantages, especially its environmental protection, aesthetics,
light pollution characteristics is to adapt to today's advocate to
create energy-saving environment-friendly society Of the trend. The
box has a strong insulation properties, chemical resistance, flame
retardant insulation, and many other advantages of good toughness.
Is the transformation of urban and rural power grid project of
choice for products.
