GENERAL INFORMATION

CONSTITUTION

Sheath

Protects the heating element from the outside. The type; of sheath depends upon the ambient surroundings and temperature of use. It offers resistance to impacts and corrosion. It is formed for the requirements of the application and is fitted with fastening accessories.; The diameter and length depend on the power and load required

Connecting terminals

Depend upon the intensity and are used to connect the heating element electrically.

Output insulation

Made of steatite or corundum to provide dielectric insulation (creepage distance, distance in the air).

Sealing material

Keeps out external moisture. Its type (silicon, resin, cement) depends upon the industrial application, the external surroundings and temperature (max. temp> for resin 150°C; max. temp, for silicone 250°C).

insulation

Electrically fused magnesium oxide for effective dielectric insulation and thermal conduction.

Resistance wire

Nickel chromium alloy, forming the active part of the heating elements.

Output rods

Make up the non heating part. Their section depends on the sheath diameter and the intensity. The length depends upon the use.

TOTAL LENGTH

Total of the lengths of the healing and non healing ports

The tobte opposite shows the length of the steel or stainless steel output rods whkh form the non heating part

SURFACE TREATMENT

Appropriate surface treatment a applied to adapt the heating elements to almost all requirements :

- Mechanical treatment: sand blasting* aluminium or zinc

plating, lead or Holar coating

- Chemical treatment: pickling, copper and stainless steel pQssivating

- Galvanic treatment: bn or nickel plating, electrolytic pohshmg.

STANDARD PRODUCTS

Standard products are stock products with the most common surface

hods, power ratings and

nxtienak (see Stock Products documentation).

ASSEMBLY PARTS

Connectors, plugs and flanges are crimped, brazed or welded. They are used to position the heating element as required by the application

IMPORTANT

For any designing jobs, we wtff require the specifications or the conditions of use of the

equipment so as to offer products whkh are perfectly suitable for

the requirements.
