Description
Technical field
The present invention relates to a kind of elastomeric material, it particularly relates to a kind of transmission cable connector training on installation special (purpose) rubber
Part composite.
Background technology
The cable connector that Utilities Electric Co. carries out employee installs the full technique operation training of overall process, it is necessary in kind with actual product
Operated, and many parts are unable to repeated application, such as rubber parts in the product（Such as rubber stress cone, it is necessary to repeatedly in electricity
Packed on cable and extracted, rubber stress cone is remained in that the size constancy shape that is the same as the original）, with what is used on actual track
Rubber parts, unit price is expensive, can expanding number of times it is few, internal diameter can forever become big irrecoverable after repeatedly expansion is installed, and can influence training
Realistic simulation effect.According to training characteristic, cable connector training on installation does not consider the electrical characteristic of cable connector rubber parts, only
Technique feel is constant when need to ensure that rubber parts is installed, therefore the production material of rubber parts is made adjustment, and meets training process to rubber
The use requirement of glue part, allows that rubber parts is used for multiple times again, so as to reduce the cost of training consumptive material.
During the present invention is in view of training installation process, installation process is mainly emphasized, and without considering final electrical property knot
Really, the requirement therefore in terms of the electrical property for just not considering material during material is adjusted, the main physical property for considering material and processing
Performance.In actual high pressure accessory product, due to there is excellent electrical property, product needed selects the rubber of second third to EP rubbers
Glue, but used as training rubber parts, EP rubbers can not meet the requirement of multiple expanding installation, mainly due to EP rubbers
Permanent deformation resistance it is poor, tear resistance is poor, low intensity, is accepted or rejected with reduces cost from physical property, natural rubber
It is fit closely material of main part.By natural rubber replace existing product EP rubbers, can expanding number of times greatly increase, can again
Multiple access times are promoted to 20 times by 5 times；And cost is substantially reduced, material cost is down to 29 yuan/kg from 80 yuan/kg.
