Standard and scope of Application
The products are used for aerial electric power transmission according to the standard GB/T 1179--2008.
Specific Property for using
1 The permissible long-time operating temperature for aerial conductor is 70°C
2 The circumstance that long distance rare climate and ice coverage rare occuring in heavy ice area , the most biggst stress of cable at the lowest arc downing point should not exceed 60% of the destructive power at a short time.
3 When connecting conductors , the conductor near to the connecting tube can not be prominent. Otherwisent, the force on the operating conductors will be unbalanced after connectors are pressed , the connecting tube should be plated by moistureproof paint in order to protect from corroding.
4 Under installation, the downing stress of all the conductors at home distance to the ground and cross building can be 10-15% higher than regular tension.
