Abstract
The utility model relates to a special shielded/armoured control cable, and the line core is the copper line with singe strand or multi strand. The utility model adopts the parallel connected polyethylene insulation and the PVC jacket. The utility model uses the copper thread or copper belt as the shield layer, and the steel belt or steel wire as the armored layer. The new shielded/armoured control cable can realize the shielding for the electric field and the magnetic field with strong anti-interfering ability, and moreover the utility model can bear a certain load or mechanical outside force, which is of a simple manufacturing technique and low cost and can meet the use of different occasion.
Description
Technical field:
The utility model relates to the cable technology field, and especially a kind of shielding that can realize electric field, magnetic field is anti-interference strong, the extraordinary shield control cable that can bear certain load and mechanical external force again.
Background technology:
Present stage is similar to cable of the present utility model and mainly contains two kinds, and the one, copper core polyvinyl chloride insulation pvc sheath steel-tape armouring control cable, its structured flowchart is as follows:
That core → 70 ℃ polyvinyl chloride insulation → stranding → PVC is with is wrapped → → steel-tape armouring → 70 ℃ pvc sheath; The 2nd, copper core polyvinyl chloride insulation pvc sheath copper strips shielding control cable, its structured flowchart is:
Core → 70 ℃ polyvinyl chloride insulation → stranding → poly-third is with wrapped---and → copper strips shielding → nonwoven fabrics is wrapped → 70 ℃ of pvc sheaths; Though according to its structure as can be seen copper core polyvinyl chloride insulation pvc sheath steel-tape armouring control cable can bear certain external force, can't realize the shielding requirements of cable; Though and copper core polyvinyl chloride insulation pvc sheath copper strips shielding control cable can satisfy shielding requirements, but it can not use in bearing the occasion of certain external force, in addition the former to adopt PVC to be with before armouring wrapped, the easy bottom pour ladle of the wrapped type bed course of this kind, broken belt and in uneven thickness, intensity is little, is easily punctured by steel band.
Summary of the invention:
The utility model purpose is to provide a kind of extraordinary shield control cable, and it can realize the shielding to electric field, magnetic field, and is anti-interference strong, can bear certain load and mechanical external force again.
The technical solution of the utility model is:
The utility model comprises core, insulating barrier, packed layer, sheath, it is characterized in that: be provided with screen and armour before restrictive coating simultaneously.
The utility model is provided with before armour and extrudes bed course.
Be respectively arranged with lapping layer before and after the utility model screen.
The utility model lapping layer comprise poly-third be with wrapped and nonwoven fabrics wrapped, lay respectively at the forward and backward of screen or back, front end.
The utility model screen is copper strips or copper wire.
The utility model armour is steel band or steel wire.
The utility model insulating barrier is that crosslinked polyethylene is made.
The utility model sheath is that polyvinyl chloride is made.
The utility model core is that sub-thread or multiply copper cash are made.
Design feature of the present utility model is:
One, is provided with screen and armour simultaneously, what have that copper core polyvinyl chloride insulation pvc sheath steel-tape armouring control cable possesses bears advantage than great machinery external force, also possess the advantage of fixedly laying occasion that copper core polyvinyl chloride insulation pvc sheath copper strips shielding control cable can be used on shielding requirements, have the unexistent advantage of the former two simultaneously again:
Two, employing extrudes polyvinyl chloride as bed course before steel band (silk) armouring, be with wrapped comparing with PVC, has following advantage: the difference of the mode of production, determined the effect difference of bed course itself, the easy bottom pour ladle of wrapped type bed course, broken belt and in uneven thickness, intensity is little, is easily punctured by steel band, the type that extrudes has exactly overcome above-mentioned defective, and withstand voltage good.
Three, insulating material difference.The insulating material that the described two kinds of cables of background technology adopt is 70 ℃ of polychloroethylene insulation materials, is cross-linked polyethylene insulating material and the utility model adopts, and crosslinked polyethylene has a lot of incomparable advantages than polyvinyl chloride.Such as: 1, heat-resistant aging is good, can be suitable for the heat proof cable insulation 90 ℃ of following long-time running; 2, electrical insulation capability is good, has high specific volume resistance, low dielectric loss and low-k, and it electrically be acted upon by temperature changes little; 3, resisting environmental stress and cracking; 4, anti-flatiron performance height; 5, good economy performance, crosslinked polyethylene be equipment and the applicability of moulding and the degree of freedom of shape from dropping into no matter, and its comprehensive economy is all better.
Four, sheath material difference.The sheath material that the described two kinds of cables of background technology adopt is 70 ℃ of pvc sheathing compounds, and the utility model employing is 90 ℃ of pvc sheathing compounds.Obvious 90 ℃ of pvc sheathing compounds are better on heat resistance, are better than 70 ℃ of pvc sheathing compounds.
Summary of benefits of the present utility model in sum is: can realize shielding to electric field, magnetic field, and anti-interference strong, can bear certain load and mechanical external force again, production technology is simple, and cost is low, can satisfy the use of different occasions.
