STEAMPETH Cable is a solid insulated, single jacket, armored air core design intended for use in underground systems where a high incidence of damage could occur if steam enters the duct. The cable is designed for application in high temperature environments up to 230°F (110°C).

Features:
• Solid polypropylene insulation
• Tightly controlled individual conductor dimensions
• Specially designed pair twist lays
• Core wrap
• Aluminum tape shield
• Steel armor bonded to the outer jacket
• Polyethylene jacket

Benefits:
• Provides higher temperature rating
• Limits resistance unbalance of paired conductors
• Minimizes crosstalk and meets the capacitance unbalance requirements
• Protects core and helps provide core-to-shield dielectric strength
• Assures good electrical contact with non-piercing bonding clamps
• Protects the core from mechanical damage and reduces possibility of tape buckling during installation, ingress of water to the shield and seepage of water along the cable between the armor and outer jacket
• Provides a tough, flexible, protective covering that withstands exposure to sunlight, above-normal temperatures, ground chemicals and stresses expected during installation

Specifications:
Conductor
• Solid annealed copper

Insulation
• Solid polypropylene insulation; standard color codes are used for pair identification

Core Assembly
• Multiples of 25-pair groups are assembled to form the final cable core; each group is identified by color coded non-hygroscopic binders; for 1,200-pair and larger, color coding is Mirror Image

Core Wrap
• Non-hygroscopic dielectric material

Shield
• Corrugated bare 8 mil aluminum tape applied longitudinally over the core wrap

Armor
• Corrugated, copolymer coated, 6 mil steel tape applied over the aluminum shield and bonded to the outer jacket

Jacket
• Black, medium density polyethylene

Jacket Marking
• Manufacturer’s identification, pair count, AWG, product identification, a telephone handset and sequential footage markings are printed at 2 foot intervals.

Standards Compliance
• Telcordia® GR-110-CORE

Applications:
• Steam tunnels
