HEATER CONNECTION
Electric heater and defrost-heater leads
Connection leads from heating or defrost elements to the terminal block. These are lead wires, not resistance heating wire.
Custom project
APPLICATION / HVAC & refrigeration
Silicone Wire for
HVAC & Refrigeration Equipment
Heater leads and internal HVAC wiring.
We build HVAC leads and cables as custom projects on our YGG silicone-sheathed construction: tinned-copper cores under a silicone sheath, rated −60 °C (−76°F) to +180 °C (356°F) continuous and +200 °C (392°F) short-term in fixed installation.
AT A GLANCE
HVAC wiring at a glance
Each HVAC connection and the silicone cable we start from.
| Connection | Cable construction | Key point |
|---|---|---|
| Electric heater and defrost-heater leads | Custom lead on the YGG silicone-sheathed construction | Lead wire only, not heating-element wire |
| Heat-exposed internal wiring | Custom YGG-based silicone-sheathed cable | +180 °C (356°F) continuous, +200 °C (392°F) short-term |
| Low-temperature and cold-room wiring | Custom YGG-based silicone-sheathed cable | Minimum operating temperature: −60 °C (−76°F) in fixed installation |
CONNECTION TASKS
HVAC & refrigeration equipment wiring
Silicone-insulated, silicone-sheathed cable is used across the industry in heating, air-conditioning and refrigeration equipment.
HEATING SECTION
Heat-exposed internal wiring
Wiring inside heat pumps, air handlers and heating sections. Give the local temperature and airflow along the route.
Custom project
COLD ZONE
Low-temperature and cold-room wiring
Connections in freezers, cold rooms and refrigerated equipment where cables must stay flexible. Define the minimum temperature during installation and use.
Minimum operating temperature: −60 °C (−76°F) in fixed installation
SELECTION CHECKS
Operating conditions to specify
Include these conditions with your enquiry so we can select the right cable.
Temperature zones
The maximum temperature near heaters and the minimum in cold sections, in operation and during installation, define the range.
Moisture & condensation
Include condensation, defrost water and cleaning chemicals in the installation requirements.
Equipment standard
The equipment safety standard and the wire approvals it requires set the documentation.

APPLICATION LIMITS
Heater leads, internal wiring & site cables
Keep connection wiring separate from heating elements and site wiring.
- Heater lead
- Connection from element to terminal: size, insulation, length and termination.
- Internal wiring
- Heat-exposed wiring in the unit: voltage, cores and local temperature.
- Site wiring
- Supply cables to the unit follow local installation codes and are specified separately.

BEFORE YOU SPECIFY
Frequently asked questions
Does ANYANG make silicone heating wire?
No. We make connection wires and cables, not heating-element wire. Heater leads are reviewed with the element drawing.
Is silicone suitable for refrigerant or oil contact?
The YGG datasheet describes limited resistance to oils and weathering. It does not specify compatibility with particular refrigerants or oil grades.
What voltage ratings does YGG cover?
U0/U 300/300 V below 0.5 mm², 300/500 V for 0.5–4 mm², and 450/750 V for the heavy version from 4 mm². The version is confirmed with your quotation.
