Example: XL2.8/10-A means:
PVC essential insulation thread heater ,diameter is 2.8mm,power 10w.
Rater Voltage, power:
1．AC 50-60HZ, Rated voltage: 6.3---400v
2. input power can be made according to customer requirement. Design within 0.5---500w
Application Field:
Refrigeratory, refrigerated display, household refrigerator, freezer and iatrical
Technical requirement: ±Φ℃
1. Electrical heater density power position tolerance <±10mm
2. Electrical heater should bear AC50HZ,1500V electric intension at least 1min in founder ,there is no hit or blink.
3. Electrical heater insulated resistance > 100MΩ in founder.
4. Expanded length 1m electrical thread whose leakage electric currency <0.2mA in working.
5. Input voltage tolerance: ≤100±10%W,>100W tolerance -10%<P<5%.
6. electrical thread insulation material and working environmental temperature :
a: PE -10℃--- +50℃ b: PVC -30℃--- +60℃
c: Teflon -65℃--- +200℃ d: Silica gel -60℃--- +250℃
7. electrical thread can be normal application after pull test under 36N for 1min.
8. electrical thread normal diameter isΦ2.8±0.2.
Structure ,characteristics and application:
1. essential insulation: cover only one kind of insulated material around of Fibreglass heater core.
Characteristics: simple structure ,competitive price and soft for easy installation. If adopt L or Y insulated material anti-impact and scratch resistance will be enforced.
2. Double insulation : On the basis of essential insulation add same or other kind of insulation material to outer.
Characteristics: Initiate technology in China. Such kind of electrical thread holds excellent insulation property. Eg. Essential insulation material is silica gel, outer insulation material adopt PVC or PE not only temperature resistance is higher but also enforce anti--impact and scratch resistance.
double insulation products commonly applied into high requirement for temperature and insulation part of refrigerator.
3. Generic safeguard: On the basis of essential insulation weave one layer of fiberglass netting.
Characteristics: soft ,easy installation, fiberglass netting protect insulation layer perfectly.
4. Assistant safeguard: On the basis of essential insulation weave one layer of metallic netting embalmed treatment on the surface.
Characteristics: soft ,easy installation, anti--impact and scratch resistance is more better than others.
Application: in refrigerator parts which more easily scratched or pressed by metallic assemble.
5. Reinforced safeguard: Put essential insulation thread into metallic tube.
Characteristics: outer shape and size can’t be changed after shaped. Holds strong anti--impact , scratch resistance and excellent heater disperse.
Application: defrost in evaporator.
