Description
Technical field
The utility model is related to a kind of shielding lines more particularly to one kind surpassing six type shielding lines.
Background technology
For six class grid lines in order to preferably obtain laser propagation effect, the interference formed between reduction is each pair of, cross is added in centre
Skeleton, product frequency can measure 250MHz, and since six class line test frequencies are high, six class lines of solid PE insulated wires production are conventional
Decaying just can guarantee qualification under 20 scale standard of temperature, and because seasonal variations temperature difference is big, fade performance is very unstable, and variation is big,
Properties of product first-time qualification rate is low, and product waste product increases.
Above six class formation has a defect that：It declines under six class line ordinary temperatures, the 20 scale standard of solid PE insulated wires production
Subtract and just can guarantee qualification, because seasonal variations temperature difference is big, fade performance is very unstable, and variation is big, and properties of product are once qualified
Rate is low, and product waste product increases.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of performance stabilization, has anti-interference energy
Power surpasses six type shielding lines.
Technical solution adopted in the utility model is：
One kind surpassing six type shielding lines, including sheath and the ground wire in sheath, and four multiple twins are additionally provided in the sheath
Cable, couple of conductor that each pair cable line respectively includes internal shield and is set in internal shield, the inner shield
Layer is outer to be also coated with thermal insulation layer and FEP flame retardant insulations successively.
Cross isolating frame, the cross isolating frame are provided in the sheath as a further improvement of the utility model,
Four pair cable line equalizations are isolated in sheath.
The conducting wire includes the conductor, endodermis, foaming being arranged from inside to outside as a further improvement of the utility model,
Layer and exodermis.
As a further improvement of the utility model, tear line and external shielding layer are provided in the sheath.
The internal shield includes polyester belt in first be arranged from inside to outside as a further improvement of the utility model,
Layer, the first aluminium foil layer and the first outer polyester layer.
The external shielding layer includes polyester belt in second be arranged from inside to outside as a further improvement of the utility model,
Layer, the second aluminium foil layer and the second outer polyester layer.
The utility model has the beneficial effects that：
The utility model one kind being surpassed six type shielding lines and shielded using pair cable line, and not only cross-talk surplus is carried
Height, and how effective protection twisted pair wire is not destroyed, and the year-on-year six classes line of cost decreases, and is effectively improved any season shadow
Decaying surplus destabilizing factor is rung, and the year-on-year six classes line of surplus index of decaying can be promoted very much.And the utility model shields inside
Also cladding outside layer is covered to increase the heat insulating function of cable equipped with thermal insulation layer and FEP flame retardant insulations and anti-flammability of burning, improve electricity
The safety of cable.
