Type 455 Class 1 Semiconductive Screened Mining Cable 3.3/3.3–11/11 kV

Type 455 mining cable without a composite insulation screen

Type 455 mining cable is the Class 1 semiconductive-screened option in this voltage group. The supplied datasheet covers 3.3/3.3, 6.6/6.6 and 11/11 kV and describes a three-power-core, two-earth, one-pilot construction for reeling and trailing service. It is listed for draglines, shovels, excavators, wharf cranes and materials-handling equipment.

The useful comparison point is construction: Type 455 uses XR-EP-90 semiconductive screened power cores, two elastomer-covered tinned earth conductors and one elastomer-covered tinned pilot. Unlike the composite-screened Type 450/451 family, this source sheet describes a semiconductive screened cable without that composite insulation-screen arrangement. The outer layer is an extra-heavy XHD-85-PCP sheath with polyaramid braid.

Select the exact voltage and area from the tables, then confirm the termination, earth/pilot functions and handling method. A model-number match does not establish mechanical interchangeability; current capacity, bend radius, pulling load and travel speed are not stated in the PDF and must be confirmed separately. Keep the cable schedule and reel data together during approval, including reel access and cable-entry clearances.

Type 455 semiconductive screened construction

Type 455 keeps the core arrangement simple and explicit: three screened power cores, two earth conductors and one pilot. Its product-specific comparison point is the semiconductive screened construction rather than the composite screen described for Type 450 and Type 451.

The supplied cross-section is placed here to show the six-core arrangement. Confirm the screen termination and earth/pilot circuit before treating another Type 455 size as a replacement.

Type 455 reeling and trailing use

The source describes Type 455 for slow reeling and trailing on mobile surface-mining and materials-handling equipment. The buyer should use the construction distinction to guide comparisons with composite-screened families.

• Draglines, shovels and excavators
• Wharf cranes and materials-handling equipment
• Slow reeling or trailing routes for the 3.3/3.3–11/11 kV range
• Equipment requiring two earth conductors and one pilot through the termination

Verify cable-management geometry, termination hardware and project mechanical limits; the source does not state a minimum bend radius, permitted pull or travel speed.

Type 455 Class 1 Semiconductive Screened Mining Cable 3.3/3.3–11/11 kV technical data

The dimensional and electrical values below are transcribed from the supplied PDF for Type 455 mining cable. The tables are retained by voltage, screen option or construction section as presented in the source. Source ordering codes are included where present in the extracted table; blank source cells are not assigned new values.

Use the relevant area, conductor dimensions, insulation or covering thickness, nominal diameter and mass together. The source does not create a universal current-capacity, bend-radius, pulling-load or travel-speed value for this product.

Type 455 source-listed limits

Type 455 is recorded in the supplied datasheet as a Class 1 semiconductive screened cable to AS/NZS 2802. The voltage family is narrower than Type 450/451 and is shown here explicitly.

Quote the exact Type 455 voltage designation and state whether the application is reeling, trailing or a materials-handling route.
