Abstract

The utility model provides a novel shielding and heat tracing cable which consists of a sheath (1), a reticular metal shield (2), a metal composite film (3), a polyester film (4), a heating wire (5), a loop wire (6) and a fiberglass yarn (7). The cable is characterized in that the wrapping material at the outsides of the heating wire and the loop wire is radiation cross-linked material which is produced through mass production in China, simple in processing technique, stable in quality and low in cost, so the technical difficulty can be reduced and the production cost can be saved. By using the metal shield to replace the earth wire, the utility model can shield the electromagnetic radiation inside the cable. The sheath of the cable is made of a PVC material and the metal composite film is wrapped by the reticular metal shield, so the heat can be conducted evenly, the electromagnetic radiation can be shielded, and the cable can be better protected, thereby having the effect of reducing pollution and protecting the environment.

Description

Novel shielding accompanying-heat cable

Technical field

The utility model relates to a kind of cable, particularly a kind of novel shielding accompanying-heat cable.

Background technology

Accompanying-heat cable relies on import mostly on present market, but the inside of import cable uses silicon rubber to do the outer wrap layer of heating line and return line mostly.Silicon rubber difficulty on the production technology is big, the production cost height, and silicon rubber output is less at home, mostly rely on imports so also to increase cost.Parcel multi-layered polyester film comes the protective wire body in the middle of the import cable, has so also increased technology difficulty and production cost.Can produce the electromagnetic radiation of trace in the cable, can influence to some extent environment.

Summary of the invention

According to problem set forth above, following solution is proposed, the utility model is made up of crust (1), net metal shielding (2), metal composite film (3), polyester film (4), heating line (5), return line (6), glass fiber (7).It is characterized in that generating heat line and return line outer wrap material is the cross-linking radiation material, and the domestic a large amount of productions of this material, processing technology are simple, steady quality, advantage such as cheap, so not only can reduce technology difficulty but also can save production cost.The utility model employing institute cable body all kinks design together, can only use one deck polyester film parcel line body just passable like this, reduce the technology of several layers of parcel, and used the net metal shielding to replace ground wire, can the interior electromagnetic radiation of shielded type cable.The utility model crust uses the PVC material, in the shielding of metal composite film outer wrap net metal, like this can more uniform heat conduction and can electromagnetic radiation shielding, and can also better protection line body, play and reduce the effect of polluting environmental protection.Use the metal composite film parcel to play the characteristics that heat conduction on average improves heat dispersion, polyester film can the protective wire body.Cross-linking radiation is all wrapped up in heating line and return line outside, and the heating line uses alloy wire to make, and return line uses copper conductor to make.The inner filled glass fiber silk of whole cable, the net metal shielding uses the metal wire system to do, whole line body parcel crust.The utility model can be worked between the 70-90 degree for a long time, and every meter cable per hour uses power to be 18W-20W.Can realize whole production domesticization fully like this, save the cost of 30%-35%, reduce the price of cable greatly.

Embodiment

Referring to shown in Figure 1, the heating line kinks with glass fiber with return line outer wrap cross-linking radiation is in the same place, and outer wrap polyester film one deck is then at mylar outer coated metal composite membrane, in the shielding of metal composite film outer wrap net metal, superscribe crust then.

Claims

1. novel accompanying-heat cable, be made up of crust (1), net metal shielding (2), metal composite film (3), polyester film (4), heating line (5), return line (6), glass fiber (7), it is characterized in that generating heat line and return line outer wrap material are the cross-linking radiation material.

2. according to the described novel accompanying-heat cable of claim 1, it is characterized in that institute's cable body all kinks design together, only use one deck polyester film parcel line body.
