Abstract
The utility model relates to a composite insulating rod, comprising a core rod. The side surfaces at two ends of the core rod are respectively provided with a left screw thread and a right screw thread; the side surface of the core rod between the left screw thread and the right screw thread is provided with an installation groove; a composite insulation layer is arranged in the installation groove; and the core rod is prepared from stainless steel or aluminum alloy or copper. The beneficial effects are provided as follows: the core rod is prepared from stainless steel or aluminum alloy or copper, thereby the integral intensity is guaranteed; the core rod performs as non magnetic conductive material, generates no eddy current or heat to lead to electric loss, and energy is saved; the core rod generates no heat, the insulating material with different thermal expansion coefficients at the external layer is not affected, cracking of the insulating portion is prevented, and the mechanical strength, service life and insulating property of the insulating layer are guaranteed.
Description
Technical field
The utility model relates to a kind of compound inslation rod.
Background technology
The plug of existing insulating rod is that permeability magnetic material is made, and intensity is low, can generate heat and cause energy loss simultaneously, affects mechanical strength, the useful life of outer layer insulation material.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of compound inslation rod.
The utility model solves the technical scheme that its technical problem adopts: a kind of compound inslation rod, comprise plug, the side at plug two ends offers respectively left-hand thread and right-hand thread, plug side opening between left-hand thread and right-hand thread is provided with mounting groove, is provided with composite insulation layer in mounting groove, and the material of plug is stainless steel or aluminium alloy or copper, plug is as non-magnetic material, electric current is not produced to eddy current, yet can not generate heat and cause the loss of electric energy, saved the energy.
Further, left-hand thread, right-hand thread and composite insulation layer are connected to overall structure, and the external diameter of left-hand thread and right-hand thread is identical with the external diameter of composite insulation layer respectively.
Further, left-hand thread, right-hand thread and composite insulation layer are connected to overall structure, and the external diameter of composite insulation layer is greater than the external diameter of left-hand thread and right-hand thread.
The beneficial effects of the utility model are: adopt stainless steel or aluminium alloy or copper as plug, guaranteed whole intensity; Plug, as non-magnetic material, does not produce eddy current to electric current, yet can not generate heat and cause the loss of electric energy, has saved the energy; Plug is owing to can not generating heat, and the coefficient of thermal expansions different for outer layer insulation material can not exert an influence, and can not cause the be full of cracks of insulated part, has guaranteed mechanical strength, useful life and the coated insulation performance of insulating barrier.
