Introduction

Interpretation of the key points of the core standard revision

Major changes Requirements of the 2016 version Requirements of the 2001 version
Expansion of multi-core structure New double-branch/triple-branch structure Only single-branch structure is allowed
Insulation resistance specification Dynamic standard for classification in Tables6-7 Fixed numerical limit

Key material technical specifications

According to Chapter 4, the materials of qualified casing are:

  • 304 stainless steel: Ra≤3.2μm
  • High purity magnesium oxide insulation: Purity ≥96%

Typical outer diameter specification comparison:

Structural type Standard outer diameter (mm) Casing wall thickness (mm)
Single branch 1.5/3.0/6.0 0.15-1.08
Double branch 3/6.4/8.0 0.14-0.97

Electrical test standards

According to the electrical strength test requirements in Table 5:

  • For bushing>3.2mm
    DC test voltage: 500V±5%
  • Grounded measuring terminal
    Head welding thickness: 0.1D~0.8D
