IGNITION CABLE, HIGH TENSION, RESISTANCE CORE (FIBER GLASS) ESE-M1L115-A SILICONE JACKET AND EPDM INSULATION (8 mm) 1. SCOPE The material defined by this specification is a high grade heat, moisture and corona resist

3、ant ignition cable, with sufficient conductor resistance to suppress electrical components in the ignition system which could cause radio interference. 2. APPLICATION This specification was released originally for material used for maximum performance in tractor and automotive type engines. 3. REQUI

4、REMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 CABLE CONSTRUCTION 3.1.1 Conductor The conductor shall consist of 60 ends of ECG 150 strand glass conduct

5、ive roving uniformly treated with carbon. An optional binder yarn, which consists of ECG 150 1/0 Z 39 tpm, may be used as a manufacturing aid. This is covered with ECG 150 1/0 Z 39 tpm, 2 ends natural glass braid using 8 heads on a 16 head braider, with 28 +/- 4 picks/100 mm and a basket (one over o

6、ne) weave. Over the braid there shall be extruded high temperature thermosetting conductive silicone. The core shall then be vulcanized (thermally cured). The finished conductor shall be smooth and have a diameter of 2.44 +/- 0.13 mm, with a minimum conductive silicone wall thickness of 0.25 mm. ENG

The diameter of the insulated conductor must not

8、 exceed 6.48 mm. The minimum diameter is limited only by the performance tests hereinafter required. 3.1.3 Reinforcing Braid The insulated conductor shall have a glass braid covering. This skeleton braid shall consist of fiber glass yarns per commercial designation ECG 150 1/0 Z 39 tpm, 2 ends natur

9、al, 16 heads, 55 +/- 4 picks/100 mm, two over and two under. 3.1.4 Outer Jacket Over the insulated conductor there shall be applied a protective coating of silicone rubber, flame, heat, corona, water and oil resistant. The surface of the finished cable shall be smooth, even and free from any tackine

10、ss due to compounds used in assembly or where specified. A minimum wall thickness of 0.51 mm must be maintained. Jacket color shall be as specified on the Engineering Drawing. 3.2 FINISHED CABLE 3.2.1 Diameter 7.75 8.26 mm 3.2.2 Resistance 16,400 +/- 6,560 ohms/m (FLTM BB 101-11, Test I) 3.2.3 Capac
