High-Voltage Silicone Wires
Custom silicone wire for 15 kV DC and 30 kV DC design briefs.
Develop the high-voltage connection as a complete package: conductor size, silicone insulation, continuous temperature, insulation wall and finished diameter. Keep continuous DC duty, AC or pulse duty and dielectric-test conditions separate.
- 15 / 30 kV DC project targets
- Insulation wall & finished size
- Defined qualification

Quality & testing
Voltage definitions
High-Voltage Wire Ratings and Dielectric Tests
A high-voltage figure is useful only when its meaning and conditions are clear.
| Electrical field | What it defines | Information required |
|---|---|---|
| Working voltage | The intended operating electrical duty | Voltage, AC/DC or pulse waveform and the operating conditions. |
| Withstand test | A specified verification condition | Test method, test voltage, duration and acceptance criteria. |
| Breakdown value | A result under defined test conditions | The method and conditions; do not treat it as a continuous working rating. |
DC design options
Custom 15 kV and 30 kV DC Silicone Wire Designs
These are custom-development targets supported by established market constructions. The agreed drawing and qualification establish the rating of the supplied cable; the factory UL 3239 dimensional table remains specific to its stated 3000 V version.
Custom 15 kV DC Internal-Wiring Design
Specify a tinned-copper single-core conductor with silicone insulation for the 15 kV DC project requirement. Choose the conductor size for the circuit and set the continuous temperature and routing envelope.
Custom 30 kV DC Internal-Wiring Design
Develop the insulation wall and finished diameter for the 30 kV DC requirement rather than reusing the 3000 V dimensions. Include the connector, stripping length, clearances and available bend space.
Conductor, Insulation and Qualification
Record conductor stranding, insulation wall, outside diameter and tolerances. Specify AC/DC or pulse duty, dielectric-test voltage and duration, and any required approval scope separately.
Enquiry details
Electrical Duty, Cable Dimensions and Test Conditions
Provide the operating requirement before choosing a size or an insulation build.
AC, DC and Pulsed Working Voltage
State AC, DC or pulsed operation and the required working voltage, including relevant peaks and test conditions.
Cable Diameter, Routing and Terminal Fit
Include conductor size, outside-diameter limit, routing and terminal or connector dimensions.

Custom & supply
Custom cable production and supply for your project
We manufacture custom cables to the agreed project specification. Share your drawing, operating conditions, quantity and delivery destination so we can define the construction, samples and supply terms.
Discuss your specification- Working voltage
- Identify AC, DC or pulsed duty and the operating-voltage requirement.
- Dimensions and connections
- Provide conductor size, finished-diameter limit, route and terminal or connector drawing.
- Tests and supply
- State the required test method, voltage and duration, documentation and quantity.
Packing & delivery
Supply lengths, labels and delivery requirements
Include the required length per coil or reel, order quantity, labelling and delivery destination. Packing method, minimum order quantity and lead time are confirmed for the project.

High-Voltage Silicone Wires: questions before ordering.
Are working voltage and test voltage interchangeable?
Treat them as separate specification fields. A test-voltage value alone does not establish the cable’s continuous operating rating.
Can you develop 15 kV DC or 30 kV DC versions?
Yes, these can be taken forward as specific custom-development briefs. The conductor, silicone insulation wall, dimensions, continuous temperature and qualification are agreed together. They do not reuse the factory 3000 V size table or imply an existing UL approval for the new design.
Is the stated kV value AC or DC?
Confirm this on the exact product specification. Include the waveform and operating conditions in the enquiry rather than assuming an AC/DC equivalence.
CABLE SELECTION & QUOTATIONS
Send your drawing or cable requirements.
You do not need an ANYANG model number. Share a drawing, existing cable marking or a description of your equipment.
Include the quantity you need and any known dimensions, voltage, temperature or movement requirements. We will check the specification with you.
