Ninomiya K-SLGB – Silica Glass Duplex Insulated K Type Thermocouple Wire

Features

Duplex-insulated thermocouple wires insulated and sheathed with silica-glass fiber. Maximum operating temperature under normal condition is 400℃, and short-time maximum operating temperature under overheating condition is 600℃ (500℃ when diameter of conductor is 0.32 mm). This series has excellent heat-resistance, electrical insulation resistance, and flexibility. The strength of the wire does not weakened so much up to maximum operating temperature of thermocouple elemental wire (under normal condition). Color of polyimide coating is natural-colored dark brown. Identification is made by spiraled stripes on the surface appeared after yarning a colored thread, which is described in the Standards Table, together with braiding glass.

Ninomiya K-SLGB thermocouple wire is duplex-insulated with silica-glass fiber, offering exceptional heat resistance, electrical insulation, and flexibility. It maintains its strength up to the maximum operating temperature of the thermocouple elemental wire (400℃ under normal conditions, and up to 600℃ briefly under overheating conditions, or 500℃ with a 0.32 mm conductor diameter). The polyimide coating is naturally dark brown, and identification is facilitated by spiraled stripes created during the yarning process with a colored thread, as outlined in the Standards Table, alongside braided glass.

• Stainless-yarn braided type, K-SL GB-SOS is also well-received, because of its reinforced outer sheath and blockage of electrical interruption. Outer diameter of this type can be determined by adding 0.6 mm to outer diameter of ordinary types shown in above table.

• Characteristics of K-SLGB
After heated to about 400℃, its strength and flexibility are unchanged. It retains excellent electrical insulation under high temperature.
