Head, to reducing failure chance, and reduce difficulty of construction, reduce expense.
A kind of 35kv and New insulated tube type bus below, it is characterised in that: it includes what ecto-entad was arranged successively
Cross section is circular oversheath, metal screen layer, external shielding layer, insulating layer, internal shield, cast copper conductor, the pipe
The center of type copper conductor is cavity structure, and the outer ring surface of the cast copper conductor is coated with the internal shield, the inner shield
The outer ring surface of layer is coated with the insulating layer, and the outer ring surface of the insulating layer is coated with the external shielding layer, the external shielding layer
Outer ring surface be coated with the metal screen layer, the outer ring surface of the metal screen layer is coated with the oversheath.
It is further characterized by: the cast copper conductor is specially highly conductive copper pipe, the section of the cast copper conductor
Area is designed according to permission current-carrying capacity and capacity of short circuit；
The metal screen layer is specially grounding body, and the metal screen layer is coated or woven copper mesh cladding using copper strips,
It makes compact-sized reliable；
The oversheath specifically uses the insulating materials of waterproof, UV resistant；
The oversheath uses LSOH anti-flaming material according to flame-retardancy requirements；
The internal shield is specially to squeeze out semiconductive insulation shield layer, makes internal shield and insulating layer, cast copper
The connection of conductor is reliable；
The insulating layer is specially XLPE/EPR insulating materials；
The external shielding layer is specially to squeeze out semiconductor conductor shielded layer, makes external shielding layer and insulating layer, metal screen
The connection for covering layer is reliable；
Branch's head is arranged in the length direction of the bus according to demand.
After the utility model, cast copper conductor is copper pipe structure, makes the length of conductor can as interior core conductor
With the production of continuous long length, and then internal shield, insulating layer, external shielding layer, metal are successively coated in the periphery of cast copper conductor
Shielded layer, oversheath improve the reliability of isolated bus, and easy for construction, non-maintaining, and it is wide to be suitable for occasion；It can be big
Length delivery greatly reduces connector, to reduce failure chance, and reduces difficulty of construction, reduces expense.
