Introduction:


High value PTC series connection electric heating band is a tracing heating cable using conductor core cable as the heating elements, used in antifreezing, anti-condensing, heat in sulation and heat compensation of long-distance transportation pipes in the petroleum,chemical and other industries, the single band design length of series connection electric heating band can be arbitrarily selected in the range of 100~5000m.

Technical parameters:


Rated voltage: ≤660V 50Hz/60Hz；
◆　Length range: 100～5000m/pc；
◆　Power range: ≤60W/m；
◆　Dielectric strength: when it is 220V the working voltage is1500V/min, when it is 380V the working voltage is 1800V/min,when it is 660V the working　voltage is 2500V/min；
◆　Explosion-proof level: ExeⅡT4；
◆　Temperature resistance level: 125℃、180℃、205℃、260℃；
◆　Material of conductive core wire: PTC alloy，nickel-basedalloy，constantan, silver-plated copper wire, nickel-basedcopper wire, tinned copper wire;
◆　Number of cores: single core, dual-core or triple-core;
◆　Heating wire resistivity range: can be selected arbitrarily withina range of0.02～0.14Ω..mm/m;
◆　Insulation material: F46, PFA, retardant silicone rubber.

Characteristics:


◆　Design subject to some certain pipe working parameters, with high reliability;
◆　Structure is scientifically reasonable, its service life is longer than other electric tracing heating band;
◆　Suitable for tracing heating pipes with longer length and fewer electricity points;
◆　Suitable for harsh and corrosive environments.

Typical applications:


Tracing heating of various fixed pipelines, pipe networks, tracing heating for long-distance conveying lines or large tanks in petroleum and petrochemical,chemical, power, chemical fibre, ports and docks,oilfields, etc.
