Q: What is an EPD Cable?
A: Engineered Product Designs- An EPD is a custom cable design created specifically for a customer, project or application using TE's Raychem components and materials.
Q: What are the appropriate applications for EPD cables?
A: Commercial Aerospace, Military Ground, Military Aerospace, Military Marine, Missiles, Outer space, Transportation- Rail/Automotive, Industrial, Offshore/Subsea
Q: When would I use EPD cable?
EPD cables are specified when the customer requires a high performance custom design solution for complex equipment connectivity.
- Small size, lightweight/weight reduction
- Ability to include signal, power, and data in the same cable package
- Specially formulated materials to meet environmental requirements i.e. low fire hazard, chemical/abrasion resistance, temperature flammability.
- Wide range of shielding solutions to address EMI/EMC requirements
- System compatibility with TE's Raychem products
- Cost savings/labor reduction over time consuming hand-built cable harnesses
Q: What specification would EPD cables meet?
A: Based on final component and material selections it could meet general commercial, military and marine specifications such as: WC-27500, AS22759, MIL-DTL-24640/24643, AS81044, VG9521 Parts 27 and 2, Defense Standard Part 25, Det Norske Veritas (DNV) and TE's Raychem internal WCD/WSD series.
Q: What temperature range of EPD cables can you offer?
From -65C to +260C.
Q: What is the maximum cable diameter you can make?
Manufactured cables are limited to a maximum cabling substrate bundle diameter of 1.75" (44.5 mm). Finished cable outside diameter (OD) would be approximately 2.0" (52.0 mm) based on this maximum substrate.
Q: What is the AWG range?
Minimum gauge size is 30 AWG and up to 2/0 AWG can be used depending on the multicore design.
Q: What is the minimum order quantity?
Between 500 ft- 2000 ft for most complex designs.
Q: What jacket materials can be used in an EPD cable?
TE offers a broad range of cable jacket materials to help meet the requirements of some of the most demanding environments.
Q: How are materials selected?
Material and component selection is determined by the end use/application. This helps to ensure the right combination of physical, chemical, and electrical properties are achieved to meet the customer's requirements. TE has also developed a system approach that groups compatible TE components.
Q: What types of components can be used in an EPD cable?
Cables can be organized with a variety of Raychem wire and cable products in controlled geometries for specific applications such as, single primary wire, twisted primaries, cabled/shielded/jacketed components, coax and data pairs and fiber. Those components can be further enhanced and/or protected by a combination of fillers, wraps, braids, jackets, armouring and blocking compounds to meet specific applications.
