Abstract
The utility model discloses an offshore oil platform cable. The cable comprises three conductor groups arranged in a triangular layout; each conductor group consists of two stranded tinned conductors, insulating layers are wrapped on the outer sides of the tinned conductors, a grounding wire is arranged on the outer sides of the two stranded tinned conductors in a contact manner, and the thickness of the tinned layers of the two tinned conductors is 0.03-0.15mm; inner belting layers are respectively wrapped on the outer sides of the three conductor groups; a shielding layer and an outer belting layer are sequentially wrapped on the outer sides of the three conductor groups respectively wrapped by the inner belting layers; a plurality of electric wires in annular distribution are arranged between the shielding layer and the outer belting layer and are in contact with the shielding layer; and an inner sheathing layer, an armor layer and an outer sheathing layer are sequentially wrapped on the outer side of the outer belting layer. In the offshore oil platform cable, the plurality of electric wires are encircled around the outer side of the shielding layer of cable, and the grounding wires are arranged close to the outer sides of the tinned conductors, the shielding layer can not get broken by an external pulling force to cause shielding failure, meanwhile, short circuit caused by contact between the tinned conductors of the cable is avoided.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of offshore oil platform cable.
Background technology:
The development of China's oil platform cable is started in the eighties in last century.Because it is very high that oil platform cable each item technical performance requires, domestic development is started late.For realizing the production domesticization of oil drilling facility-specific cable; Domestic have cable factory to succeed in developing 2000V and following offshore oil and warship ship power cable with reference to GJB1916-94 " naval vessel is with low smoke cables and flexible cord general specification ", the standard IEEE 45-1998 of AAEE " the boats and ships electrical installation rules that IEEE recommends " and the requirement of the U.S. DAA-1048B of SURPENANT company technical specification, tentatively realized the production domesticization of oil platform and naval vessel cable.
The utility model be applicable to exchange or direct current 440V and following boats and ships and offshore oil platform in being connected and telephone communication equipment of various instrument and communication apparatus, cable can stand the withstand voltage test of 50HZ2000V5min.
Oil platform cable to original does not have electric line usually at screen, and screen breaks off the effect that does not have shielding owing to drawing high sometimes, causes the shield effectiveness of cable not good; Sometimes because the insulating barrier breakage causes two zinc-plated cores to contact, these outer cable two core groups (conductor group) can be short-circuited after the contact phenomenon.The utility model adopts around the electric line of outer ring winding number root of the screen of cable, is provided with an earth connection the outer next-door neighbour of tinned conductor, has solved above-mentioned problem effectively; In addition, the tin coating ground thickness of cable is carried out technologic improvement, improved economic benefit.
The utility model content:
To the prior art problem, the purpose of the utility model provides a kind of offshore oil platform cable, makes the shield effectiveness of cable not cause losing efficacy because of external force draws high to break off, and has solved the phenomenon that the cable tinned conductor contacts and is short-circuited.
The technical scheme of the utility model is following:
The offshore oil platform cable; Comprise three conductor groups; Described three conductors are formed isosceles triangle and arranged, and it is characterized in that: described three conductor groups are enclosed with all by the outside respectively that two tinned conductors of insulating barrier are stranded to be constituted, and two tinned conductors outsides after stranded are provided with a contacted earth connection; The tin coating thickness of described two tinned conductors is 0.03-0.15mm; Described three conductor groups outside is enclosed with interior belting layer respectively, is enclosed with screen, outer belting layer successively outside three conductor groups behind the belting layer in the parcel, is provided with several electric lines that circularize distribution between described screen and the outer belting layer; Described electric line contacts with screen, and described electric cross-sectional area is not less than 0.25mm
2, the described outer belting layer outside is enclosed with inner restrictive coating, armour, external sheath layer successively.
Described offshore oil platform cable is characterized in that: described armour adopts the tinned copper wire braiding to constitute, and count is not less than 85%.
Described offshore oil platform cable is characterized in that: described screen adopts the aluminium-plastic tape that is not less than 0.06mm overlapping wrapped.
Described offshore oil platform cable is characterized in that: described insulating barrier adopts crosslinked polyethylene.
The utility model has the advantages that:
The utility model adopts around the electric line of outer ring winding number root of the screen of cable, is provided with an earth connection the outer next-door neighbour of tinned conductor, makes shielding not cause losing efficacy because of external force draws high to break off, and has solved the cable tinned conductor phenomenon that is short-circuited that contacts simultaneously; In addition, the tin coating ground thickness of cable is carried out technologic improvement, improved economic benefit.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The offshore oil platform cable comprises that 1, three conductor group 1 of three conductor groups arranges in a triangle; Three conductor groups 1 are enclosed with all by the outside respectively that two tinned conductors 3 of insulating barrier 2 are stranded to be constituted; The tin coating thickness that two tinned conductor 3 outsides after stranded are provided with 4, two tinned conductors 3 of a contacted earth connection is 0.03-0.15mm, belting layer 5 in three conductor group 1 outsides are enclosed with respectively; Belting layer 5 back three conductor group 1 outsides are enclosed with screen 6, outer belting layer 7 successively in the parcel; Be provided with several electric lines 8 that circularize distribution between screen 6 and the outer belting layer 7, electric line 8 contacts with screen 6, and electric line 8 sectional areas are not less than 0.25mm
2Outer belting layer 7 outsides are enclosed with inner restrictive coating 9, armour 10, external sheath layer 11 successively, and armour 10 adopts the tinned copper wire braiding to constitute, and count is not less than 85%; Screen 6 adopts the aluminium-plastic tape that is not less than 0.06mm overlapping wrapped, and insulating barrier 2 adopts crosslinked polyethylene.
