BIRNS® Size "P25N" (Penetrators)

BIRNS® Size "P25N" (Penetrators)

BIRNS penetrators transmit electrical power/signal through a pressure boandary, decrease the complexity of electrical systems, and reduce dependence on operator skill. NPT Penetrators have tapered "pipe" threads and are widely used on diving bells and decompression chambers. BIRNS NPT Penetrators are made with AISI 316 stainless steel shells, passivated per QQ-P-35 type VI. They are rated for use up to 80º C (176º F) when fabricated with neoprene (polychloroprene) cable jackets, or up to 95º C (203º F) with optional CSPE cable jackets.

Features

All BIRNS penetrators are uniquely serialized and certified
All BIRNS penetrators are tested and certified per ABS/DNV - compliant BIRNS test procedure ETP-6510-101
All BIRNS penetrators are tested with helium to 150% design pressure inboard (before and after termination and overmolding) and with hydrostatic saltwater testing to 150% design pressure outboard
ABS or DNV witnessing of testing is available at additilonal charge; customer witnessing is free of charge
LSZH (Low-Smoke Zero-Halogen) penetrators are available for ABS/DNV -rated use; these are designated by the suffix "-LS" and have individual LSZH wires inboard
Special cable jackets (e.g. Hypalon or po.yurethane) and types (e.g. TSP) are available on request
