Description

Cable insulating device.

Object of the invention

The purpose of this utility model is referred to a cable insulating device comprising two layers, one of plastic material and another based on polyurethane, of such that it allows easy placement on distribution lines electric, with voltage on said line, as well as a protection effective for birds, avoiding the electrocution of birds.

Background of the invention

To date it is unknown by the inventors, experts in the field of any type of insulator electrical for distribution cables in high and medium lines voltage, so that said insulator prevents electrocution of the birds that perch on these wires.

So far to avoid electrocution is they use inn deterrents (like bird silhouette) that result ineffective as well as insulating coating systems of dangerous elements of the pole that present problems of Aging and fall

Description of the invention

The insulating device for cable lines electrical distribution comprises at least a first layer of flexible extruded plastic protection, one length approximately 1.2 to 1.5 meters, so that it can be placed in the post fastening systems and where the system Rigid plastic protection is placed directly on the cable, in tension by a dry blow of the pole, and understanding in addition said first layer of own means that prevent its fall, twist or undock of the cable. The device is completed with a second protection layer of the clip that joins the cable to the crosshead said second layer consisting of a foam coating 80% polyurethane insulator placed by spray allowing its placement with tension in line.

We can consider the possibility as an advantage of tension placement since it greatly lowers costs, on the other side allows placement in any crosshead design and for any type of cable (it is only necessary to modify the diameter in cable radius function), staple insulation in addition It provides greater security to the system. Another advantage to be obtained directly from the design is the impossibility of falling or decoupling of the system as well as resistance to aging and the high safety margin provided by the dielectric capacity  of the material.

Brief description of the figures

Then it goes on to describe very brief a series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention presented as a non-limiting example of is.

Preferred Embodiment of the Invention

As can be seen in the figure attached, the insulating device of line cables electrical distribution comprises, in a preferred embodiment, the less, the insulation of the cables through an EPDM protection (Ethylene-Propylene-Diene-Monomer) placed in post fastening systems and with a length approximately 1.5 m. in this way there would be enough space for that the birds make their supports without risk of electrocution, so how to insulate the clip that joins the cable to the post to reinforce its effectiveness.

This protection device will be a profile (1) performed by extrusion of red insulating EPDM with a radius interior (2) that will fit the different cable sections and a thickness of 4 mm to 5 mm. The profile (1) will have two tabs (3) exterior, the total size being 38 mm. The design provides a total cable cover (4) and tabs (3) allow its placement by tension dry blow by means of a pole without its fall, return, turn or decoupling of the cable (4) is possible.

The device is completed with another layer of protection of the clip that joins the cable (4) to the crosshead to make the insulating device even safer and therefore offer greater protection for laying through a coating with 80% Polyurethane, that would be placed without air ( airless in Anglo-Saxon terminology) also allowing its isolation in tension.

Claims (3)

1. Cable insulating device of electrical distribution lines characterized in that it comprises at least: a first plastic protection profile (1) flexible extruded, so that it can be placed in the tension clamping systems by means of a dry blow of pole; where said profile (1), in turn comprises:

a first zone circular radio adaptable (2) to the different cable sections electric (4), and

own means that prevent its fall, twist or decoupling of the cable, said means consisting of two tabs (3) emanating from the first zone circular (2).

2. Insulation device according to claim 1 characterized in that it further comprises a second protection layer of the clip that joins the cable to the crosshead, said second layer consisting of a coating of 80% polyurethane insulating foam placed by spray, allowing its placement with tension in line. 3. Insulation device according to claim 1 characterized in that the first profile (1) of extruded flexible plastic protection is approximately 1.5 meters long.
