In the intense radiation vacuum of space, and in the core components of aerospace instruments, every signal transmission and every power supply must be flawless. Today, we’re introducing a core product designed specifically for extreme scenarios—aerospace-grade polyimide insulated lightweight conductors (TST-HKTPI 300V / TST-HKTPIP2 300V), using cutting-edge technology to safeguard every breakthrough in the aerospace industry!

Hardcore configuration, forging aerospace-grade quality
As a “dedicated conductor” in the aerospace field, this product has achieved extremely stringent requirements in terms of materials and structure:
Conductor: Silver-plated conductor or silver-copper alloy conductor is used, which strictly complies with GJB773A-2000 standard, with excellent conductivity and outstanding oxidation resistance;
Insulation and sheath: Both adopt PI (polyimide) extrusion process, which is resistant to high temperature and aging, and provides solid protection for the core performance of the conductor;
Shielding layer: Also uses silver-plated conductors or silver-plated silver-copper alloy conductors to effectively isolate external interference and ensure stable signal transmission.
Superior performance, fearless of extreme challenges
To establish oneself in the aerospace field, one must withstand various extreme tests:
Wide operating temperature range: Operating temperature range is -220℃ to +260℃, can withstand high temperatures of +300℃ for short periods, and can work normally even in extremely low temperatures of -269℃. It will not “break down” no matter how large the temperature difference is.
Radiation-resistant pioneer: Easily resists alpha and gamma rays. When the irradiation dose reaches 1×10⁸rad, the tensile strength change rate is ≤±15%. Even if the dose is increased to 1×10⁹rad, the insulation and sheath surfaces will not crack.
Withstand voltage: Rated voltage 300V AC, AC test voltage up to 1500V AC, DC test voltage up to 3600V AC, with maximum insulation performance;
Mechanical strength: The minimum bending radius during fixed installation is only 3 times the outer diameter of the cable, and it can withstand more than 10,000 abrasion tests without being easily damaged;
Safe and environmentally friendly: High flame retardancy, low smoke, halogen-free, and non-toxic, meeting the EN45545-2 fire resistance HL3 level requirements, making it safer to use.
With outstanding advantages, it leads the industry standards.
Compared to similar products, its core competitiveness is obvious:
Compared to existing PI film-wrapped wires: it has higher voltage resistance, is lighter in weight, and is easier to install and use;
Compared to standard AS 22759/180-192 products: lighter weight, smoother surface, and more suitable for precision instrument assembly;
Compared to the MIL-W-22759 standard product: lighter weight, smaller outer diameter, saving installation space, and superior surface smoothness.
Multiple specifications are available to meet diverse needs.
Whether it’s critical connections in spacecraft or internal wiring for instruments, we can provide suitable specifications and solutions:
TST-HKTPI 250V Series (Unshielded)

TST-HKTPIP2 250V Series (with shielding)

Widely used, protecting critical areas
The applications of this conductor are found in core aerospace scenarios:
Strong radiation vacuum environments such as outer spacecraft, satellites, and space stations;
Internal wiring and connections for aerospace instruments and meters;
Key components such as motor windings.
From ground testing to space exploration, from precision instruments to power systems, this polyimide-insulated lightweight conductor, with its superior performance and reliable quality, has become an indispensable “signal and energy bridge” in the aerospace industry.
