Abstract

The utility model discloses a transmission line cross-arm comprising a cross-arm body covered with a passivation layer. Since the cross-arm body covered with a passivation layer employing advanced passivation technology, different colors applied on the surface of a pole-tower which has already plated zinc become permanent after being heated at a continuous high temperature. On one hand, the passivation layer provides anti-oxygen protection and greatly prolongs the service lifetime of the cross-arm, on the other hand, the color on a pole-tower can be used as a fixed identifying signal for different lines to alarm workers climbing the pole-tower about the danger of the tower and prevent workers from climbing a live tower, thereby ensuring a safe working environment for a cross-arm.

Description

The transmission line of electricity cross-arm

Technical field

The utility model belongs to electric power power transmission and transformation component technical field, is specifically related to a kind of transmission line of electricity cross-arm.

Background technology

" electric power safety operational procedure " clearly stipulated, when wiring on the same tower multiloop electrical power connection device, every basic shaft tower all should be provided with obvious identification marking, as colour code, differentiation flag etc.What generally adopt in production run at present, is that the method for cross-arm mopping realizes identification marking.But because shaft tower is in the field for a long time, be subjected to the destruction of natural conditions easily, just needed colour code of brush in average per 3 years, brought very large workload for operation maintenance department.Simultaneously, because the effect that the rust preventing on the shaft tower, cross-arm can not solve basic isolation oxygen, so the application life of cross-arm is unsatisfactory.

In addition, circuit is more near transformer station's outlet, and parallel shaft tower is also a lot, and the bar type is similar, is easy to mistake and steps on charged parallel shaft tower, brings very big potential safety hazard for the construction workman, does not have good solution at present.

The utility model content

The utility model provides a kind of transmission line of electricity cross-arm that can avoid mistake to step on charged shaft tower, parallel shaft tower.

A kind of transmission line of electricity cross-arm comprises the cross-arm body, and the outside of described cross-arm body is provided with passivation layer.

Because the utility model is provided with passivation layer in the outside of cross-arm body, passivation layer adopts advanced passivating technique, and different colours is painted on the tower material surface of tiding over zinc, realizes the permanence of shaft tower color with the method for continuous high temperature oven dry.On the one hand to a kind of oxygen barrier protection of providing of cross-arm itself; improved the application life of cross-arm widely; what is more important; the obvious color of difference and shaft tower itself of cross-arm behind the passivation layer is set, and color is beautiful, obvious, but long preservation (50 years); as required on the tower material that the differentiation flag of circuit can be solidified; be easy to carry out reminder alarm, avoid occurring mistake and step on electrification phenomenon, improved the safety guarantee of cross-arm related work stepping on the tower workman.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a transverse sectional view of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2: a kind of transmission line of electricity cross-arm, comprise cross-arm body 1, the outside of described cross-arm body 1 is provided with passivation layer 2.

Because the utility model is provided with passivation layer in the outside of cross-arm body, passivation layer adopts advanced passivating technique, and different colours is painted on the tower material surface of tiding over zinc, realizes the permanence of shaft tower color with the method for continuous high temperature oven dry.On the one hand to a kind of oxygen barrier protection of providing of cross-arm itself; improved the application life of cross-arm widely; what is more important; the obvious color of difference and shaft tower itself of cross-arm behind the passivation layer is set, and color is beautiful, obvious, but long preservation (50 years); as required on the tower material that the differentiation flag of circuit can be solidified; be easy to carry out reminder alarm, avoid occurring mistake and step on electrification phenomenon, improved the safety guarantee of cross-arm related work stepping on the tower workman.

Claims (1)

1. a transmission line of electricity cross-arm comprises the cross-arm body, it is characterized in that: the outside of described cross-arm body is provided with passivation layer.
