Halogen Free Fire Retardant (Flame Resistant) Control Cable

Specifications

Property and function: the products of halogen-free low smoke fire retardant (flame
resistant) control cable are provided with excellent mechanical physical property,
electrical property, fire retardant (flame resistant) property, and also with
properties of halogen free, low smoke, etc. This product is suitable for controlling
and monitoring return circuit and protecting line with rated voltage 0.6/1kV
and below, which requires specially fire safety, such as tall buildings, metros,
oil platforms, computer centers, nuclear power stations, hospitals, ships,
etc.

Properties of application:
1) Max. rated temperature of the conductor is 90oC
2) Max. short-circuit temperature of the conductor shall not exceed 250oC
3) Max. sustaining period not exceed 5 seconds
4) Installation temperature of cable shall not below 0oC
5) Recommended permissible bending radius:
    a) For non-armored cable, shall not be less than 6 times of the cable's overall
        diameter
    b) For armored or copper tape shielded cable, shall not be less than 12 times
of
        the cable's overall diameter
    c) For soft cable with shield layer, shall not be less than 6 times of the cable's
        overall diameter

Construction specifications of cable:
1) Conductor: round solid or twisted conductor is adopted for the conductor of the
    cable, its construction and resistance accord with the requirements of GB 9330-88
    in "plastic insulated control cable"
2) Insulation: the XLPE is adopted for the insulation material; fire-retardant insulation
    material consists of two parts: wrapped mica tape and XLPE. Mica tape is high
    temperature insulation material, it may be not breakdown for 3 hours, at
    temperature 1073K and voltage 1,000V
3) Filling and wrap: insulated conductor is twisted to cable, and the gap between
the
    finished cables is filled with halogen-free low smoke fire retardant strand.
The
    wrapped material adopts halogen-free low smoke fire-retardant tape, overlapped
    wrapping
4) Undersheath and oversheath: the halogen-free low smoke fire retardant polyolefin
    material, adopted in both undersheath and oversheath, is a special material for
    halogen-free, fIfe-retardant, low smoke and low toxicity polyolefin cable, with
    excellent extrusion and fire-retardant properties, operating temperature is 90oC
