3MScotchcast

Signal and Control Inline Splicing

Kits 72-N Series


 

 

 

Data Sheet

 

Product Description

 

3M Scotchcast Inline Splicing Kits 72-N Series is a series of rigid body splices tailored for joining signal and control cables. The kits are designed to accommodate shielded or unshielded constructions of plastic or rubber-jacketed cables. Six kit sizes cover a range of cables up to 100-pair (200 conductors) 10 AWG or 200-pair (400 conductors) 22 AWG.

 

The 72-N series splice consists of a rigid-body mold filled with pliable polyurethane 3M Scotchcast Electrical Insulating and Sealing Compound 2104.

 

Jumper wires with clips provide for shield continuity on shielded cables. Built-in spacer webbing automatically provides for cable centering and proper compound coverage. The kits are sized for, but do not include, 3M Scotchlok Insulated Butt Connectors. The completed splice is designed and tested for direct burial.

 

Kit Contents

 

Each kit contains sufficient quantities of the following materials to make one (1) splice, excluding inline connectors:

 

 One two-part translucent mold body with tongue and groove seams and built-in spacer webbing

 

 3M Scotchcast Electrical Insulating and Sealing Compound 2104 in convenient 3M closed mixing pouch

 

 Two pour spouts for kits 72-N1, 72-N2, and 72-N3; one top cap cover for kits 72-N4, 72-N5 and 72-N6

 

 Scotch ® Rubber Splicing Tape 23 for constructing sealing collars and sealing splice body ends

 

 One nonconductive abrasive cloth for preparing cable

 

 One bonding (jumper) wire with clips for providing solderless shield continuity on shielded cables (except 72-N1 kit)

 The 72-N2 through 72-N6 kits will accommodate shielded or unshielded cable. The 72-N1 kit is recommended for unshielded cable only

 

 Convenient kits simplify ordering and stocking

 

 Kits provide all materials needed to reinsulate, reconnect shield, and rejacket one splice

 

 Compound has low viscosity for fast, complete filling of splice

 

 Compound has low exotherm which will not damage plastic insulated cable

 

 Convenient closed mixing pouch container permits clean, easy compound handling

 

 Polypropylene mold with built-in spacer web automatically provides for cable centering and compound coverage

 

 No special tools required; normal hand tools only

Data: Physical and Electrical Properties

 

3M Scotchcast Inline Splicing Kits 72-N Series can be used on cable that operates continuously at 90°C (194°F) and has an emergency overload temperature rating of 130°C (266°F). The splices are rated at 1000 volts.


 

Moisture-Resistance Test

 

Thermal cycling submerged in water pressurized to simulate a 1.8 m (6') head: the splice 72-N series exceeds 1.0-x-10 6 ohms insulation resistance after ten temperature cycles of 2°C to 24°C (35°F to 75°F).
