Silicone heating wire specification

Silicone heating wire specification

First,Product overview

Silicone rubber heating wire has excellent heat resistance, it is widely used in refrigerators、freezers、 air conditioning,、drinking fountains、rice cookers and other household appliances. The average power density is generally below 40w / m. The power density can up to 60w / m with using  temperature of -60 ℃ - +155 ℃ under a better heat dissipation environment.

According to the different characteristics of the using，our company has two kinds of silicone rubber heating wire: parallel constant power heating wire and self-limiting heating wire.

Second,Product Model

1.Parallel constant heating wire

(1) Application:Building, Cold storage, heating ground of warehouse,heating chute,gutter and roof defrost.

(2) Feature

A.Good temperature performance.All insulation materials is silicone(include power cable).It can work between -60C and ±200C.

B.Good thermal conductivity.Power can produce heat, direct thermal conductivity, high thermal efficiency, short-term heating to achieve the effect.

C.Reliable electrical performance.Each electric heating tape need to be test for rigorous DC resistance, flooding high pressure and insulation resistance to ensure quality before leaving factory.

D.Strong structure, flexible and easy to be bent.Combined with the overall cold end, no binding point. It has reasonable structure and is easy to be installed.

E.Can be designed.Heating length,length of power cable,rated voltage and power all can be customized.

2.Self - limiting heating wire

(1)Instructions：The heating wire is on the glass fiber wound alloy wire, and its outer layer is covered with silicone rubber insulation layer.Dameter:φ01.2/2.0 /2.5/3.0/4.0/5.0/mm；Resistence：0.3-20000Ω/m；Temperature resistance:180/90 centigrade;appication:freezer、air condition、Freezer defrosting heat，Rice cooker insulation、electric blanket、electric cushion、electric massage chair、medical beauty equipment、electric waistline、electric thermal clothing、electric heating shoes、bath pool、foot basin and so on.

(2)Specifications can be customized:

A、The connection between the heating wire and the outgoing cold end (lead wire) is sealed with silicone mold，But the lead wire must also be silicone insulation.  

B、The connection between the heating wire and the outgoing cold end (lead wire) is sealed with a shrink tube.

C、The connection between the hotline and the cold end leads has the same diameter as the wire body，mark the heat and cold section with color markings.The advantage is that the connection with the line body has the same diameter, simple structure.

Third,note

1.Parallel constant power heating wire can be cut at any length in the the longest limit use.

2.Self-limited wire is limited by the heating wire use length and power,can not be cut at any length.
