Description
Technical field
The utility model relates to be provided with rail bar or the busbar connector field of multiple separation link positions for matching piece, specifically relate to
And a kind of hot-face insulation copper bar.
Background technique
During high-building construction, there are many places to transmit electrical energy using power cable.It has many excellent
Point, the shortcomings that also having it: big specification power cable between floors long length installation, in use process, cannot there is low-angle
Or right angle installation, it otherwise can damage the structure of power cable.
Utility model content
The utility model is intended to provide a kind of hot-face insulation copper bar, is not suitable for building to solve big specification power cable
The problem of long length low-angle or right angle are installed and used in object.
In order to achieve the above objectives, the basic technology scheme of the utility model is as follows: a kind of hot-face insulation copper bar, including copper are led
Body, the outer layer of copper conductor are surrounded with thermal insulation tape, and the outer layer extrusion molding of thermal insulation tape has the layer of resistance to ambient dielectric, resistance to environment
Insulating layer is silane crosslinked halogen-free low-smoke flame-proof polyolefin layer.
The principle and advantage of this programme are: copper bar compares big specification power cable, is guaranteeing same power transmission performance
Simultaneously because its section is allowed to have smaller setting angle in same sectional area there are a wider side.But it is traditional
Copper bar is mostly exposed in use, and although heat dissipation is preferable in this way, the electric current passed through in copper bar is larger in the environment, produces
Raw heat is higher, the danger for easily causing overheat even to ignite neighbouring wire and cable.Be exposed to outer copper bar be also easy by
Influence to environment generates corrosion, and environmental resistance is poor, and there is also biggish electrical shock safety hazards.When practical application, copper conductor
As electric conductor, thermal insulation tape forms the insulating protective layer directly contacted with copper conductor, has preferable electrical insulation properties
With heat and flame resistant performance, wrapped form can comprehensively coat copper conductor and be superimposed to form reliable and stable insulating layer,
The layer of resistance to ambient dielectric as outer layer insulation protect, have good environmental resistance, be mainly used for low temperature resistant, ultraviolet light, high temperature,
Anti-aging, waterproof, moisture-proof etc..The copper bar with double insulation protection is formed in this way, and internal layer has good heat resistance
And electric property, can it is conductive to copper conductor after high current, high voltage insulate, to the copper conductor to generate heat after conduction carry out every
From preventing spontaneous combustion；Outer layer has excellent environmental resistance, can protect internal copper conductor not by extraneous ring after contacting with the external world
Border influences, and also forms insulating layer and avoids generating leaky.It is resistance to using silane crosslinked halogen-free low-smoke flame-proof polyolefin insulating materials
Environment capacity is very good, and very well, when burning does not have for low temperature resistant, ultraviolet light, high temperature, anti-aging, anti-flammability, waterproof, moisture-proof etc.
There is or seldom exists toxic smog, long-term use temperature can greatly reinforce outer at 125 degree, by the way of natural-crosslinked
The comprehensive performance of insulation；It is halogen-free factor in silane crosslinked halogen-free low-smoke flame-proof polyolefin insulating materials, so that producing, making
With, recycling entire link in, environmental pollution is seldom.
The hot-face insulation copper bar formed in this way, since it is allowed to keeping excellent big specification electric power for long row pattern in structure
Also the double-deck hot-face insulation that can be carried out normal mounting use while transmission performance under low-angle or right angle context, and use
Protective layer is more suitable for carrying out the high-power electric power of long length between floors with the excellent resistance to ambient dielectric performance of fire resisting
Transmission, and usage safety performance is high.
Further, thermal insulation tape is mica tape.As preferred mica tape excellent electric properties, and fire and heat endurance ability
By force, electrical isolation effectively can be carried out to copper conductor and high temperature is isolated.
Further, the section of copper conductor is rectangle, and the seamed edge of copper conductor is circular arc smooth transition.As preferably setting in this way
It sets so that copper conductor has a bigger connection area, when use connects more stable, and the seamed edge of circular arc smooth transition can avoid in rib
Point discharge is formed at side causes insulating layer to damage.
Further, silane crosslinked halogen-free low-smoke flame-proof polyolefin layer is squeezed out using tubular molding tool.As preferably setting in this way
Set the tensility that can make full use of material, and extrusion process will not because copper conductor any bending caused by insulating layer core shift.
Further, Mica tape has at least two layers, and the lapping direction of adjacent two layers mica tape is opposite.As preferably in this way
More comprehensively effective cladding can be carried out to the surface of copper conductor by being arranged, and squeeze out silane crosslinked halogen-free low-smoke flame-proof polyolefin layer
During mica tape will not because of the pushing of silane crosslinked halogen-free low-smoke flame-proof polyolefin material generate displacement, formation it is interior absolutely
Edge layer is more reliable and more stable.
Further, the silane crosslinked halogen-free low-smoke flame-proof polyolefin layer of copper conductor end extends to form protective sheet outward.
As be preferably placed such that in copper bar in use, the end of copper conductor be connected in equipment after by protective sheet can be to connecting portion
It is blocked, avoidable accident touches copper conductor end and causes electrical shock safety accident, and also avoidable foreign matter falls in copper and leads
The connection influence of end effect power transmission of body.
Further, protective sheet far from the end in the middle part of copper bar integrally formed with fixing belt, fixing belt close to protective sheet one
Multiple jacks are distributed in end along its length, and the free end of fixing belt is integrally formed with inserting column.As can preferably use in this way
Fixing belt is tied up in the equipment for being wound on connection by the connection of inserting column and jack in the process, is blocked so that protective sheet is stable
On the outside of copper conductor end and the junction of equipment, so that protective sheet is more preferable to the protecting effect of junction.
