Product Overview

Carbon-free rubber hose, also known as carbon-free insulated hose, is a professional high-insulation protective hose for high-temperature electric furnaces and high-voltage equipment. Made of high-grade insulating rubber and multi-layer polyester thread reinforcement, the hose features compact structure, pressure resistance and tensile resistance. The carbon-free insulated design prevents electric leakage and voltage breakdown, with excellent weather resistance, no hardening, cracking or aging under long-term high temperature and outdoor conditions. Complete specifications with inner diameter 13-200mm and optional colors, it is widely used for cooling water delivery and inert gas transportation of high-frequency heating equipment, fully meeting high-voltage insulation standards.

High Insulation Performance

This hose has excellent high insulation performance and strong anti-breakdown ability, working stably under 40000V live environment. With ultra-high insulation coefficient and resistance up to 10¹⁵ ohms, it effectively avoids electric leakage risks and ensures operational safety for workers and equipment. It can withstand 6000V rated voltage with stable and long-lasting insulation performance, suitable for long-term continuous operation in high-voltage and live working conditions.

Technical Features

Adopting special carbon-free formula, the hose is highly insulated and completely non-conductive, perfectly meeting the operation needs of high-frequency induction heating equipment. Professionally developed for silicon furnaces and induction furnaces, it is highly suitable for furnace circulating cooling water systems with outstanding high temperature resistance and insulation protection. Flexible and corrosion-resistant, it can convey hot water, hot air and inert gas. With stable structure and compression resistance, it maintains stable performance without deformation in high-frequency and high-temperature environments.

Difference Between Carbon-free Hose and Ordinary Hose

1. Material: Carbon-free hose adopts insulating rubber and polyester thread; ordinary hose is made of steel wire, cloth clip and conductive rubber.
2. Insulation: Carbon-free hose has ultra-high insulation and 10¹⁵Ω resistance; ordinary hose has poor insulation and cannot be used in high-voltage occasions.
3. Application: Carbon-free hose is dedicated to electric furnaces and high-voltage insulated environments; ordinary hose is only for conventional water and gas delivery.
4. Safety: Carbon-free hose prevents electric leakage and breakdown; ordinary hose is conductive with great hidden dangers under high voltage.

Application Scope

Widely used in special occasions requiring high voltage insulation protection, for conveying hot water, hot air and inert gas. It is supporting equipment for intermediate frequency furnaces, induction furnaces and silicon furnaces. Commonly used for water cooling cable cooling in steel mills, as well as metallurgy, chemical industry, mining, shipbuilding, engineering machinery and other fields, which is an essential insulated pipeline for industrial high-temperature and high-voltage equipment.
