Abstract
The utility model discloses a long-span lead, which comprises a twisted bearer and a twisted lead core, wherein the lead core is coated outside the bearer which is made of steel core. The lead core is an aluminum wire core. In the long-span lead provided by the utility model, the structure that an aluminum lead is coated outside the twisted steel core is adopted and the tensile strength of the aluminum lead on the steel core can be increased, so that the aluminum lead can meet the requirement of long-span power transmission.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of 500kV and above large span lead of being applicable to.
Background technology
In growing, if adopt aluminum steel to make lead merely because the problem of aluminium tensile strength difference does not fit into the transmission of electricity of large span apart from the high-tension transmission process.
Summary of the invention
The purpose of this utility model is that a kind of lead that is suitable for the large span transmission of electricity will be provided.
The purpose of this utility model is achieved in that a kind of large span lead, and lead is made of stranded supporting body and stranded lead core, and the lead core is coated on outside the supporting body.Supporting body adopts steel core to make.The lead core is an aluminium matter core.
The large span lead that the utility model provides owing to adopted stranded shaped steel core to coat the structure of aluminum conductor outward, by steel core having been increased the tensile strength of aluminum conductor, makes aluminum conductor can adapt to the needs of large span transmission of electricity.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is made of stranded supporting body 1 and stranded lead core 2, and lead core 2 is coated on outside the supporting body 1.Supporting body 1 adopts steel core to make, and lead core 2 is an aluminium matter core.
Claims (3)
