Product Overview
High voltage relays are electro-vacuum relays designed to maintain insulation and transfer circuits under sustained high potential. The contacts are sealed in a ceramic-to-metal vacuum body, keeping the contact gap separate from the surrounding environment and preserving the specified internal insulation structure during operation.
Typical uses include high-voltage communication modules, radar high-voltage sections, pulse equipment, automatic grounding systems, and control or insulation circuits that remain at high potential for long periods. Model selection should cover operating voltage, open-contact withstand voltage, coil-to-contact insulation, contact form, and the external clearance around the terminals.

Core Advantages
High-voltage ratings by frequency
JPK-13/013 lists working-voltage values from DC/50 Hz to 32 MHz. RF and high-voltage control circuits can be checked at their actual operating frequency instead of using one voltage value for every condition.
DPDT transfer for two high-voltage paths
Its two-pole changeover contact transfers two isolated circuits with one operating mechanism. Paired signal, grounding, or polarity-transfer paths therefore receive the same switching command without two separate relays.
Specified open-state insulation resistance
JPK-13/013 is rated at no less than 10,000 MOhm across open contacts and from contacts to case. This gives measurement and control circuits a stated leakage limit for selection and incoming verification.
Customization
High-voltage specification
Working voltage, open-contact withstand voltage, insulation requirements, make/break duty, and contact form.
Coil and terminal configuration
Coil voltage, pickup and release requirements, terminal type, terminal orientation, and external connection layout.
Equipment interface
External dimensions, mounting method, panel or board connection, and modification from JPK-13-013, an approved drawing, or a reference sample.
Quality Control
Incoming inspection checks ceramic bodies, metal seals, contact parts, coils, terminals, and insulation components for dimensions, surface condition, and model compatibility. Before furnace processing, technicians verify the internal contact geometry, ceramic-to-metal fit, and the relationship between the contact unit and high-voltage terminals.
The finished relay is tested for insulation and withstand voltage according to the confirmed model, then checked for contact resistance, coil operation, and switching response. Release requires the relay model, terminal position, mounting interface, label, electrical results, and order specification to agree.
Why Choose Us
Quality control for high-voltage products
Wanping's quality system covers incoming parts, vacuum processing, electrical testing, aging, final inspection, and batch release, with military product quality management system certification.
High-voltage testing capability
Production and test equipment is used to verify insulation, withstand voltage, contacts, coils, and switching performance in sealed electro-vacuum relays.
Production controlled by the full model
JPK-13-013 and modified versions are built to the confirmed contacts, coil, ceramic size, terminal arrangement, and mounting interface rather than judged by external appearance.
FAQ
Q: Can I order one relay for equipment verification?
A: Yes. Available standard models can be supplied from 1 piece for installation and electrical checks. A modified model moves to sample production only after the specification and drawing are confirmed.
Q: What packaging is used for high voltage relays?
A: Each relay is identified by model and packed so the ceramic body, high-voltage terminals, coil leads, and mounting parts cannot strike each other. The quantity and transport route determine whether reinforced export cartons or cases are used.
Q: Does the internal vacuum insulation eliminate the need for external clearance?
A: No. The vacuum chamber controls insulation inside the relay. The surrounding equipment must still provide the required creepage, clearance, shielding, grounding, and insulation around the terminals.
Q: Can the coil remain energized continuously?
A: Only coils rated for continuous duty should remain energized. The selected coil voltage, allowed voltage variation, ambient temperature, ventilation, and temperature rise must all stay within the model data.
