Include a cable unit less；It is coated with first screen layer, secondary shielding layer and outer shield successively inside-out on the cable core
Layer, the first screen layer, secondary shielding layer, the cross section of outer jacket and conductor chamber are in rectangular configuration.
In said structure, the conductor chamber sectional area due to insulating barrier and filled with copper conductor is in rectangular configuration, is easy to
The laying of electric wire is fixed, and it is fixed will not form installation rotational displacement, and it is smooth attractive in appearance to lay profile, especially more
When bar electric wire is arranged in juxtaposition, this square cable can realize that gapless is superimposed, and will not both form mutually extruding and twisted change
Shape, cause that laying space availability ratio is more rationally compact again.Again due to being formed cable core with square cable unit, therefore in reality
Using when multiple cable unit combinations can be carried out depending on requirement, meet that the cable of various facilities lays needs, there is combination
Flexibly, advantage rational in infrastructure, neat appearance is attractive in appearance.Due also to it is coated with the first screen in the cable core that square cable unit is formed
Cover layer and secondary shielding layer, so constitute dual shield structure can effectively block cable power transmission electromagnetic wave to external radiation,
Interference of the electromagnetic wave caused by transmission current to electrical equipment is avoided, so as to ensure the reliable and effective transmission of signal, it is ensured that electricity
Son, the safe operation of electrical equipment.This square cable can also be adapted well to the connection needs of the square interface of particular cable.
The ︰ 1 of the ratio between preferred embodiment of the present utility model, the cross-section lengths a and width b of cable unit a ︰ b=2.
The cable core includes two cable units, and the cross section of the first screen layer, secondary shielding layer and outer jacket is in pros
Shape.Neat appearance is attractive in appearance, is easy to securely lay fixation.
Further embodiment of the present utility model, 2-4 copper conductors are provided with the conductor chamber.Conduct electricity very well,
It is compact-sized reasonable.
Preferred embodiment of the present utility model, the copper conductor are twisted by some copper wires, and each copper conductor is twisted
Direction is identical.Copper conductor is twisted with some copper wires so that cable has good flexibility, is easy to laying installation；In the same direction
The twisted structural stability that can keep copper conductor.
Preferred embodiment of the present utility model, the first screen layer are foil shielding layer.The secondary shielding layer is
Woven shield.Aluminium foil layer has shielding and a moistureproof, airtight advantage, and woven shield is in addition to good shielding,
Also there is preferable flexibility.
Preferred embodiment of the present utility model, the insulating barrier and outer jacket are poly- by radiation low-smoke non-halogen flame-retardant crosslinking
Ethene, which extrudes, to be formed.The oversheath has excellent physical characteristic and good insulation protection performance.
