Self-limiting heating cable

The products are imported from ISOPAD Company in U.K.; one of the major electric surfaces heating companies in the world. The product are manufactured according to BS standard of British and has been approved by EECS, The products quality come to the recently world advanced stage.

The products power drop(self-limiting) is very small and long-lived; It can auto-adjust the power output to the varying conditions along the pipe. Self-limiting properties occurs at every point the length of cable, The self-limiting effect allows the cable to be overlapped without creating hot spots or burnout. It is suitable for requiring heating-trace in comprehensive heat field.

ISL, PSL self-limiting cable heating construction (See chart)

ISL, PSL is suitable for industrial applications where temperature excursions to 85°C(185°C)or process temperature maintenance to 65°C(120°C)may be experienced and can be cut at any point to fit paperwork, Owing to self-limiting properties. It produces a uniform heat field. It has been widely used in power stations, offshore installations, pert-chemical, building services and food processing. It has ordinary range (/TC-)and strengthen range(/TC-).Ordinary range is suitable for use in non-hazardous areas and strengthen range is suitable for use in hazardous areas.

Fuse/ circuit breaking sizing

Installation method

1. The selection and installation of the power cable, Use copper wire, cross-sectional area≥1.5cm2. It’s better to choose low smoke and non halogen wire. The connection wire of power cable should be divided into the following color :

1, Phase - the same as the power color

2, N line - Blue insulated wire

3, PE line - Interphase as green and yellow insulated wire

Joint method of power cable and heating cable

Firstly deal with heating cable conductor leader insulation. Then deal with the power and heating cable conductor joint according to the electrical wiring rules.

The end blocking method of the heating cable

1, Firstly, cut the end, separate the end and the conductor, attention: The end of two conductors is strictly prohibit articulated.

2, Using high-pressure self-adhesive tape wrapped end to 2cm, then wrapping one more layer with PVC waterproof tape, prevent high-pressure self-adhesive tape shedding and aging.
