CN2927266Y - T-shaped electric cable - Google Patents

Abstract

The utility model discloses a T-shaped cable, matched with the geothermal and electro thermal system, and the construction process is simple, convenient and clipping. The T-shaped transfer point is precast, pressure casting molded by a plurality of insulating layers, has a better insulating ability, a longer one-off period of usage, and is maintenance-free. The utility model is made of component conductors and insulating layers, characterized in that: conductor 1 is the copper core with an insulating layer 2, two or three conductors appose together, at the T-shaped conversion position the conductor is connected in parallel with the corresponding T-shaped conductor end 3, an external insulating layer 4 with a whole structure is pressure injected outside of the T-shaped connected conductor, the external insulating layer 4 can be made of the electric insulation material which is universal at present, the T-shape can also be replaced by a ''cross'' shape, or the combination of a plurality of ''cross'' shaped and T-shaped conductors.

Description

T type cable

Technical field:

The utility model is a kind of high-insulativity cable, specially is used for T type transit cable..

Technical background:

At the underground cable of burying underground, owing to be to be embedded in the cement face under or to bury in the deep layer soil property, be subjected to environmental corrosion, the useful life that requires it higher insulating properties and the reliability that is connected to be arranged and grow.And present this cable is linear, when being used to do the switching of T type, needs in-situ processing, often easily cause the weak spot of insulating properties and connection reliability, and construction is inconvenient.Special higher to cable insulation and the easy construction requirement buried underground under the cement flooring in ground electric heating facility.

Summary of the invention:

The utility model purpose is to disclose a kind of T type cable, and supporting with the ground electric heating system, the work progress simple and convenient is quick.Transit point is prefabricated forms for T type electricity, the multilayer insulation injection-compression molding, and good insulation preformance, disposable long service life, non-maintaining.

The utility model is made up of lead and insulating barrier, it is characterized in that: lead 1 is the copper core that has insulating barrier 2,2 or 3 lines are arranged side by side, go out corresponding T type conductor wire end 3 in the parallel connection of T type conversion place lead, the integrally-built external insulation layer 4 of pressure injection one deck outside the T molded lines that connects into, external insulation layer 4 can be present general electrical insulating material, and described T type can be+font, also can be the combination of a plurality of+font or a plurality of T molded lines.

Description of drawings

Fig. 1 is the utility model structure cutaway view;

Fig. 2,3,4 is respectively the external form figure of enforcement of the present utility model.

Embodiment:

The utility model the inside is that copper core 1 is led in power supply, one deck is just arranged itself or insulation more than two layers.Its T type switching place is that electrician's tradition connects, and makes insulation processing in the junction in case of necessity.One layer insulating of outermost is the T molded lines to be connected the unified compression moulding in back form, and its thickness of insulating layer is about 1-3 a times of diameter of wire.Because a pressure injection is hermetically sealed at T molded lines upper conductor, does not have any dew point.Whole cable hardness and rigidity make cable be difficult for bending, can be because of the bending distortion fracture, be particularly suitable under the cement flooring, doing between the permanent electric hot cell or with external power between be connected.

Claims (1)

1. T type cable, form by lead and insulating barrier, it is characterized in that: lead (1) is the copper core that has insulating barrier (2), 2 or 3 lines are arranged side by side, go out corresponding T type conductor wire end (3) in the parallel connection of T type conversion place lead, the integrally-built external insulation layer of pressure injection one deck (4) outside the T molded lines that connects into, external insulation layer (4) can be present general electrical insulating materials, described T type can be+font, also can be the combination of a plurality of+font or a plurality of T molded lines.
