Uniprene Cables

Wiring cables for Aircraft and Ships

Mansfield manufactures comprehensive range of air-frame wiring and ancillary cables to meet conditions of air-frame wiring and ancillary cables to meet conditions of aircraft and ships. Cables conforming to B. I. S., British Standards or defence specifications can be supplied in accordance with customer requirements.

Mansfield

also supplies minature cables and flexible equipment wires for testing/Laboratory purposes apart from composite and Grab cables.

The cables are resistant to Toxic Vapour, oils and heart and are robust with other distinctive properties. Many aircrafts wiring cables are also suitable for industrial applications.

Pren Aircraft Wiring Cables

Mansfield Pren aircraft wiring cables which are suitable for use at established conductor temperature upto 90oC, conform in all respects to BS: 2E: 21 (Pren type electrical cable for aircraft).

Cable Designations

  • Pren: Single core cables having tinned copper conductors covered with a glass fiber and polychloroprene insulation. Multicore cables consist of single core cables laid together and having an overall glass fibre braid with a lacquer varnish finish.
  • Prenal: Single core cables similar to Pren but having an aluminium conductor in place of tinned copper.
  • Prenmet: Single core and Multicore cables similar to pren with an overall braid of tinned copper wires

Quality

In the manufacture of cables, standard lay down operating procedures at each and every stage are followed to achieve quality. For quality end products, control starts from proper design of the product. All raw materials are selected carefully and only materials of high quality are used in production. Having done this, stage wise inspection is done to ensure conformity with relevant Indian/International Standards.

Tests

The tests on cables have been classified broadly in four categories as follows:

Routine Tests

Tests carried out on each Cable to check the requirement which are likely to vary during production.

Type Tests

Tests carried out to prove conformity with the specification. These are intended to prove the general qualities and design of a given type of cable.

Acceptance Tests

ests carried out on samples taken from a lot for the purpose of acceptance of the lot.

Optional Tests

Special tests are carried out when required by agreement between the purchaser and the manufacturer. Special tests required for FRLS Cables can also be carried out at our works i.e. Halogen gas generation test to IEC-754 (part-1) , Smoke generation test to ASTMD-2843, Oxygen Index test and Temperature Index test to AS T MD -2863, Flammability test to (1) IEC -332-3., flame resistant test to IEEE-383.
