Specific implementation mode
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and detailed description are as follows for attached related data.
Before implementing a kind of nuclear power station radiation areas cable tie method provided by the invention, binding strap is first determined
Material and model.The material of binding strap selects it is required that binding strap is durable, and in the present embodiment, binding strap determination is given birth to
Produce cable copper braid over braid.The coefficient of expansion of production cable copper braid over braid meets the cable coefficient of expansion, will not damage cable.In order to full
Requirement of the foot to the irradiation of the high temperature resistant of binding strap, the model of the copper braiding binding strap in the present embodiment：It is straight that copper weaves binding strap
Diameter is more than 3mm, and the width after flattening is not less than 5mm, and copper braiding binding belt surface is at least coated with one layer of shielded layer, shielded layer single layer
Thickness 0.5mm, it is tin plating again on the surface of shielded layer.
Copper weaves the model of the docking copper pipe of binding strap crimping：Outer diameter 7.00mm, internal diameter 1.00mm, length 10.00mm.
It is completed in the cable laying of nuclear power plant reactor workshop radiation area, and the cable in cable testing bridge is collated complete
At cable will lay one, arrange one, bind one.Since this one end of equipment (forbid since that end of cable reel,
In order to avoid waste cable) arrange, bind successively to that end of cable reel, reasonable length is reserved according to device location.On vertical channel
Cable is bound every at most 3 feet of spacing, is fixed on crane span structure
Cable tie is proceeded by from equipment end, in conjunction with attached drawing, a cable is often bound and all uses following methods：
Copper is woven band level in 1 lower section of crane span structure strut rail of nuclear power station radiation areas, and copper is woven band by the first step
One a of end and two b of end penetrate the rear of the cable 2 for being close to crane span structure strut rail 1, and copper braiding band is in 1 front of crane span structure strut rail
It is horizontally disposed, horizontal segment is formed, copper weaves band right-angled intersection after 2 rear of cable is wrapped in crane span structure strut rail 1；
Second step turns down forward one a of end for intersecting at the copper after crane span structure strut rail 1 and weaving band, penetrates copper braiding and pricks
Band and the gap in cable 2, two b of end that copper weaves band are equally turned down forward and are woven on the horizontal segment of band as copper
Side；
Third step, one a of end and two b of end that the copper in second step is woven to band twist into one, take up；
4th step, the loose portions that copper is woven to band are cut, then docking copper pipe is penetrated and twists into one copper braiding bundle
Band innermost end will dock copper pipe with Press Plier and compress, and will finally dock the extra copper braiding band part of tube end and cut.
The present invention takes full advantage of that durable, the high temperature resistant irradiation of copper braiding, that thermal expansion coefficients meet cable heat is swollen
Swollen coefficient does not hinder the characteristic of cable.The method that banded cable is woven with copper is simple, practical and reliable.With the construction of three generations's nuclear power
Development, higher and higher to nuclear safety requirement, by extensive use, this copper is compiled for the cable tie fixation of reactor building radiation areas
Knit banded cable can be used for other nuclear power plant reactor workshop radiation areas cable tie it is solid.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
