HI-DENSITY CARTRIDGE HEATERS IN METRIC SIZES

Home    软文    HI-DENSITY CARTRIDGE HEATERS IN METRIC SIZES

Standard sheath material is 321 Stainless Steel which provides good thermal conductivity, and resistance to corrosion and scaling. Welded end disc made from the same material as the sheath provides a positive seal against moisture and other contaminants. Grade “A” Nickel-Chrome resistance wire precisely wound on a high purity magnesium oxide core places the resistance wire as close to the inside of the sheath as possible. A high purity Magnesium Oxide (MgO) powder is used to fill all remaining space inside the sheath. Heater is then swaged, which compacts the magnesium oxide grains into a solid mass. The standard termination for is Type N, 10" (254 mm) long nickel conductor lead wires externally connected to solid conductor terminal pins.

1.Single-Ended Straight Termination

The Electrical Termination is located at one end of the heater and exits straight out from the heater.

2.Double-Ended Termination

Each end has one Electrical Termination.

ELECTRICAL TERMINATIONS

Type N: External Pins with Leads

Flexible stranded lead wires have fiberglass insulation and are connected to 1-1/4" (32 mm) long solid conductors. Silicone rubber coated fiberglass sleeving insulates the pin/lead wire connection.

Type F: Internally Connected Flexible Leads

The fiberglass lead wires are internally connected to the terminal pins. This lead termination provides flexibility, permitting the lead wires to be sharply bent as they exit the heater.

Type M1: Polyolefin Liquid Barrier

A liquid barrier used for low temperature applications primarily in refrigeration or food service applications. The seal bonds to both the heater and the leads.

Type M2: Potted End Seal

Potted end seals help to protect the heater from moisture or contamination from plastic material, cleaning solvents, or oils. The bottom end disc seal is welded in.

Type M3: Teflon® End Plug Seal

A moisture resistant Teflon® seal that is swaged in during the manufacturing process with Teflon® insulated lead wire.

Type SA: Sealed Corrugated Armor Cable

A liquid-proof stainless steel corrugated metal hose is silver brazed to the end of the cartridge heater. The end disc of the heater is also welded or brazed. This termination provides a positive seal against moisture and contamination entering the heater.

Type S1: Flexible Spring

The leads are reinforced with a steel spring for applications with extreme flexing. The spring is mechanically fastened or silver brazed.

Type S2: Right-Angle Spring

The leads are reinforced with a steel spring for applications with extreme flexing. The spring is mechanically fastened or silver brazed.

Type W1: Right-Angle Wire Braided Leads

Stainless steel braid over fiberglass leads for abrasion protection, mechanically crimped to the cartridge sheath at 90°. Wire braid offers extreme flexibility not possible with armor cable. Various lead end finishes are available as listed below.

Type C2: Right-Angle Armor Cable with Copper Elbow

Armor cable provides the maximum in protection for abrasive, jagged environments. The copper elbow between the cartridge and the armor cable is mechanically fastened or silver brazed.
