Tape: Glass Cloth

(High temperature elctrical wiring tape)

  • Glass Cloth Tape No.27 is a high heat splicing tape composed of a glass cloth locking and an adhesive that thermosets in high heat application environments. It is a Class B 266°F (130°C) electrical insulation.
  • Catalog No.27 – 1/2″ wide x 66′ long
Cement: High Temperature

  • This cement insulates electricity but radiates heat. It also resists acids, oils, and temperatures up to 3000°F. This is the same cement Backer Hotwatt uses in electric heating elements and can be used for electric kilns, furnaces, and resistors. The cement hardens into a porcelain-like body by air drying without the use of kilns or injury to the finest resistant wire.
  • Catalog No. C-78, 1 Quart Container.

WIRE: HIGH TEMPERATURE HOOK-UP

Features

  • The high temperature insulated wires are for use in internal wiring of domestic, commercial,and industrial heating, cooking, and process equipment.
  • Wires are suitable for service up to the rated voltage in damp and dry applications with wire temperatures up to 250°C (482°F); with intermittent use in ambients as high as 650°F.
  • Wires are identical to that used on our own heating elements.
  • Available in 100 foot and 250 foot spools.

RESISTANCE WIRE: NICKEL CHROMIUM

Features
  • Backer Hotwatt’s nickel-chromium wire (80ni-20cr) is proven to deliver outstanding performance over extended periods of time and is the same wire we use in our own electrical heating elements.
  • Uniformity of resistance.
  • Mechanical stability
  • Fine surface finish
  • Consult factory for specifications on other sizes and different alloys which are available. Typically Iron-Chromium-Aluminum alloy, Nickel-Iron Alloy, and Thermocouple Alloys.
