Shielding Unshielded, PurposeUse Industrial Wiring, Type Single Core, AF-250 PTFE Insulated Hook-Up Wire High-Temperature Hook-Up Wire, Bing Cable

Product Overview

Our factory specializes in the supply of PTFE high-temperature wire and cable, including the AF-250 series – a premium range of PTFE insulated hook-up wires designed for demanding high-temperature applications. With continuous operating temperature up to 250°C and voltage ratings covering 250V, 600V and 1000V, the AF-250 series delivers reliable performance in compact, weight-sensitive, and chemically harsh environments.

Available insulation materials include PTFE, FEP, PFA, and ETFE, with conductor options of silver-plated copper or tinned copper, in solid or stranded constructions. The product line covers a full range of AWG 9 to AWG 34, with custom sizes available upon request. As a specialty PTFE insulated wire expert, we offer complete customization to meet your specific project requirements.

Key Features & Advantages

3. PTFE Insulation Outstanding resistance to oils, acids, alkalis, chemicals, and aging – ideal for complex industrial environments

4. Three Voltage Grades AF‑250‑2Q (250V), AF‑250‑2 (600V) and AF‑250‑2H (1000V) – easy system voltage and installation space matching

5. Broad Application Base Aerospace equipment, semiconductor manufacturing, industrial automation, electro‑thermal equipment, medical devices, electronics.

FAQ

Q1: What are the differences between AF-250-2Q, AF-250-2 and AF-250-2H?

The primary differences are rated voltage and insulation thickness: AF-250-2Q is a 250V compact type, AF-250-2 is the 600V standard type, and AF-250-2H is the 1000V heavy-duty type. Final selection should also consider conductor size, finished O.D. and equipment-level standards.
