To ensure the overall firmness, the sheath 2 and the solid insulator 1 are integrally injection-molded and connected; the suspension fitting 3 is used to fix the wire. Since the suspension fitting 3 is wrapped outside one end of the solid insulator 1, it is convenient to make the connection area between the suspension fitting 3 and one end of the solid insulator 1 larger, so that the connection performance of the two is good, ensuring the overall firmness of the three-proof insulating cross arm of the present application; the fixing fitting 4 is used to connect with the connecting fitting 6 of the relevant transmission pole. Since the fixing fitting 4 is wrapped outside the other end of the solid insulator 1, it is convenient to make the connection area between the fixing fitting 4 and the other end of the solid insulator 1 larger, so that the connection performance of the two is good, ensuring the overall firmness of the three-proof insulating cross arm of the present application; since one end of the sheath 2 is wrapped outside the suspension fitting 3 and the other end of the sheath 2 is wrapped outside the fixing fitting 4, it is convenient to make the connection areas between the sheath 2 and the suspension fitting 3 and the fixing fitting 4 all larger, so that the connection performance is good, ensuring the overall firmness of the three-proof insulating cross arm of the present application; the three-proof of the present application specifically refers to the solid insulator 1, the suspension fitting 3, and the fixing fitting 4.

[0060] Furthermore, asFigure 6 The suspension fitting 3 includes: a suspension fitting body 31; and a gland 32 connected to one end of the suspension fitting body 31 through a fastener 33. Wherein, the other end of the suspension fitting body 31 is wrapped outside one end of the solid insulator 1, and one end of the sheath 2 is wrapped outside the other end of the suspension fitting body 31.

[0061] Specifically, the suspension fitting body 31 and the gland 32 fix the wire through the fastener 33, which is convenient for ensuring the tightness of the wire.
